Understanding The Differences Between Core i5 And i7

Posted by Brad Wasson in "Digital Home Talk" @ 06:30 AM,281...,2404674,00.asp

"Discounting Core i3 (mainly found in budget systems) and AMD processors (another article entirely), the difference between Intel Core i5 and Core i7 can seem daunting, especially when the prices seem so close together once they're in completed systems. We break down the differences for you."

Have you ever wanted a summary of the differences between these two processor families? If so, a recent PC Magazine article may help. While both processors are infinitely capable, there are some benefits to the Core i7 family in certain circumstances. The article compares the processors along the lines of price and marketing, performance, cache, turbo boost, hyper-threading, and integrated graphics. It is not a deep-dive by any means, but it is a nice summary.

Hardwarecanucks Examines Intel's Sandy Bridge-E Core i7-3960X CPU

Posted by Lee Yuan Sheng in "Digital Home Hardware & Accessories" @ 08:39 AM

"The flagship Core i7-3690X Extreme Edition is a 32nm six-core/twelve-thread processor with a 3.3Ghz default clock, but which never ever dips below 3.6GHz and tops out at 3.9GHz in single and dual-threaded workloads. Accompanying these six cores is 15MB of L3 cache, the most of any desktop processor, and a new beefed up memory controller that features a quad-channel DDR3-1600 interface which is theoretically capable of 51.2GB/s of bandwidth."

A Sandy Bridge 6 core CPU starting at 3.3 Ghz sounds impressively fast, but I am not sure many are willing to shell out the $990 list for it. I suppose it is only for the most hardcore users (or those whose work heavily depends on fast encoding of videos); for the rest of us, a nicely overclocked i5-2500K will do quite well for many things.

Is That Old Clunker Ready For The Scrap Heap?

Posted by Hooch Tan in "Digital Home News" @ 11:00 AM,2717.html

"An increasing number of enthusiasts are likely wondering whether their systems are still fast enough, or if it makes sense to invest in an upgrade heading into the holiday season. Many people jumped on the Athlon 64 or Athlon 64 X2 because of great performance and strong overall value in the first half of the last decade. "

It is easy getting caught up in the race for the fastest computer on the block. What was peppy and powerful one day quickly becomes old and sluggish the next. That does not seem to be the case so much anymore these days as computers, even three years old, are plenty powerful for today's applications. I just hope those that do upgrade find good homes for their old friends. For years now, we have had incredible computing power, much of which holds up against everyday needs. I can remember years back, a hand-me-down computer that was three years old at the turn of the decade, or even in the 90s would have problems keeping up with what was demanded of it. Now, people work well with computers that are much older than 3 years. Since I work with technology, what I use in my office is a mishmash of things new and old. Owing to budgetary constraints, I rarely have anything that is bleeding edge, and I do admit to having some things that I use which are approaching a decade in age. What about you? How old is your gear? Does it still fulfill your needs?

New CPUs and Prices from Intel

Posted by Lee Yuan Sheng in "Digital Home Hardware & Accessories" @ 05:30 PM

Alright, so I am a little late on this one, but Digitimes has some interesting rumours, and the one that really caught my eye was the i7-950 getting a huge discount. Makes me thinking whether it was just a slightly higher clocked but overpriced i7-930 to begin with.

There's also the hex core i7-970, but at that price of US$885 in bulk quantities, I think I'll keep my money thank you very much. As usual the highest end is low on value; stick to something like a quad core i7-860. Hit the link to find out more.

Tom's Hardware Compares Four Quad-Core Architectures At 2.8 GHz

Posted by Jason Dunn in "Digital Home Articles & Resources" @ 06:00 AM,2499.html

"AMD and Intel are relentless when it comes to diversifying their respective CPU portfolios across every possible corner of the processor market where someone might want to spend money. The good news is that these efforts give us lots of technology options across the entire price spectrum. But buyers who don't follow the daily cadence of processor development couldn't possibly know whether Core i7 or Core 2 Quad is the newer product, or how these compare to AMD's own line of obscurely-named models. In some ways, it doesn't matter which chips were launched most-recently. The more important consideration might be which processor offers the best total performance relative to its peers, and one of the best ways to judge this is with a shoot-out at a given clock rate."

If you're up to date on the performance merits of each major CPU type, this article won't be a shocker - but if you're not a hardcore CPU geek and are curious about where each of the major chips from Intel and AMD rank in relation to each other, this article is worth a read. I won't spoil the results for you, but it boils down to this: if performance matters to you more than money, buy an Intel chip. If the reverse is true, buy an AMD chip.

Intel Talks About CPUs for 2010

Posted by Jason Dunn in "Digital Home News" @ 11:19 AM

"Intel has just concluded its first CES press event of 2010, dedicated to "announcing" the already well known Arrandale and Clarkdale CPUs. They will be part of Intel's planned 27 total SKUs coming in 2010, including four varieties of Core i3, eight Core i5s, and five Core i7 models. We were treated to a demo showing off a Core i5 laptop CPU running a 1080p video with another video stream overlaid on top of it with a measly 10% CPU usage."

Much of this leaked before CES, but there's still some good info to be had here. Highlights include an Intel wireless solution dubbed Centrino Ultimate-N 6300, which has three receive antennas and throughput of 450mbps, a Core i5 CPU that has two cores and four threads clocking in at 3.33 Ghz with a turbo boost up to 3.6 Ghz and a price tag of $196 USD. What's a bit surprising is that out of all the CPUs they announced, there's a lack of high-end CPUs...only the Core i7 860 is on the matrix with four cores and eight threads, and that's not a new CPU. Engadget mentions there's another Intel press conference tonight, so I expect that's where the high-end CPUs will get announced. We should be hearing about six-core i7 processors with twelve threads. Yowzers!

HP's Core i7-based Desktops Plagued by Problems?

Posted by Jason Dunn in "Digital Home News" @ 03:00 PM

"Hewlett-Packard customers are up in arms about a major glitch affecting the company's Core i7-based PCs. A HP forum containing a shedload of gripes about the technical cockup - that some suggest may have been caused by a defective motherboard - runs to over 100 pages. A Reg reader told us that HP's line of Intel Core i7 CPU-loaded computers were locking up, freezing and regurgitating blue screens of death. He added that the vendor's Elite Pavillion Series appear to be particularly hampered by the nasty glitch."

It's sometimes hard to tell when a technology problem is wide-spread, because people with the problem tend to complain loudly while people without the problem quietly go about their business...but this seems like a legitimate issue with HP's Core i7 systems. Any Digital Home Thoughts readers bitten by this problem?

Is That a Mobile Core i7-920XM in Your Pocket...

Posted by Hooch Tan in "Digital Home News" @ 08:30 AM,2443.html

"Thus, when you see a 130W desktop-class Core i7 (Bloomfield) CPU shoehorned into a laptop, you don’t expect much in the way of battery life (to be fair, Thomas got nearly an hour out of Eurocom’s D900F). That’s like trying to get a V8 under the hood of a Prius—totally defeats the point, even if there is a small contingent of folks who can actually put that self-contained horsepower to use."

It had to happen eventually. While there are companies who are more than willing to stuff a desktop CPU into a laptop sized casing, Intel has finally made a Core i7 CPU designed specifically for the mobile market. As with most high-end, eats Prime95 for breakfast, processors, the resulting laptops tend to be more transportable, then mobile. Tom's Hardware got their hands on a Eurocom Cougar, which features the Core i7-920XM and predictably, the 920XM does best the Core 2 Extreme QX9300 it is being compared to. Still, if one can hold out for just a few more months, Tom's notes that the next generation, Arrandale, should provide comparable oomph with much better mobility. Having a 17" behemoth myself, I can honestly see that Arrandale will be the CPU to keep an eye out for. Anyone waiting for a laptop to sport this powerhouse, or does mobility win out in your mobile choices?

Eurocom's D900F Panther For Serious Workers Only

Posted by Hooch Tan in "Digital Home News" @ 01:00 PM,2354.html

"Designed to serve as either a portable replacement for a mid-range graphics workstation or a high-end game machine, the D900F Panther features Intel’s fastest Core i7 Extreme desktop processors, RAID support for up to four drives and, purportedly, the user’s choice of Nvidia’s latest GeForce or Quadro graphics."

It was only a matter of time before Core i7 CPUs worked their way into laptops. While Eurocom's attempt uses the older Core i7-965 Extreme CPU, it still represents the top of the line kind of laptop where one favours horsepower over weight, size or portability. Not surprisingly, the Panther is a 17" laptop, which seems to be the minimum size for mobile workstations and desktop replacements. Yes, it is capable of gaming, but the monster seems designed more for workstation performance so for those of you wanting to process video or other CPU/GPGPU intensive tasks, this is the laptop to go for. I've got a 17" heavyweight myself, and while it does not compare to the portability of netbooks, when you need to get a real amount of work done, nothing compares. For details, check out Tom's review.

Laptops get the Core i7 Treatment

Posted by Hooch Tan in "Digital Home News" @ 02:00 PM

"When it arrived on the desktop scene, Intel’s Core i7 levelled the opposition. With enough power to embarrass Intel’s own Core 2 architecture, not to mention AMD’s efforts, and coming at a cost that would make even a banker weep, Core i7 set the benchmark and set it high. Now it’s set to repeat the trick in the laptop market, and we’ve got our hands on a sample boasting the mid-range quad-core 1.73GHz i7-820QM."

With the recent announcement of the updated Core i7 CPUs, Intel is looking to bringing the number crunching wonder to the laptop world. PC Pro has a peek at what we can expect from laptops equipped with the Core i7 hotness and what extras Intel has tossed into the mix that could see better battery life, well, for performance oriented laptops at least. TurboBoost definitely looks interesting, and I can see many applications where it could help things along, such as encoding videos, file compression and the like. Still, I do not see Core i7 laptops being available for anyone but the mid to upper range laptops for a while, especially with cost concerns and a draw of 74 watts. Of course, wait long enough, and we will eventually see netbooks offering this kind of number crunching muscle.

Intel's Core Family is a Happy Family

Posted by Hooch Tan in "Digital Home News" @ 07:30 AM,2410.html

"Of course, that’s only really funny for the folks who’ve already seen how the Lynnfield-based processors actually perform and know they’re not as anemic as an enthusiast might expect, given the fact that Intel is aggressively pursuing integration, aiming for a SoC-type design in the not-so-distant future. But Clarkdale is six months away, at least. Today is all about Lynnfield—the Core i5 and Core i7 CPUs for Intel’s LGA 1156 interface."

When Intel first came out with its Core i7 processors, they smacked all other CPUs around and cost enough to fund the American auto industry. It is now nearly a year later, and Intel has decided that mere mortals should now be able to have access to extreme computing power and have updated the Core i7 and introduced the Core i5 a more reasonably priced powerhouse. Tom's Hardware gives you the skinny, putting the new CPUs through the usual tests and noting the changes between generations and the improvements made such as on Turbo Boost. The takeaway from all this is that Intel is keeping busy trying to maintain its performance crown, but has made the mid-range pricing much more competitive. Whether you favour Intel or AMD, expect prices to be quite juicy in the coming weeks!

Intel Relaxes Limitations on i7 CPUs

Posted by Hooch Tan in "Digital Home News" @ 09:00 PM

"If you’ve tried to research the differences between Intel’s top-end Core i7-965 Extreme Edition and the midrange 940 and budget 920 parts, you’re probably as confused as us. And we even have direct access to Intel. But the technical differences between these parts are enormously important for system builders when you consider the price disparity -- $1000 for a Core i7-965 compared to under $300 for a Core i7-920."

According to correspondence between MaximumPC and Intel, the Core i7 920 and 940 can be boosted more than originally planned. At their base configurations, the 920 and 940 already provide an increidble amount of horsepower, but with the added features of having an unlocked QPI and memory multipliers, the Core i7 series stands to be a solid value and those dreams of using a Phenom II for me are quickly dismissed. I hope Intel doesn't change their mind, as I know what I'll be getting come next upgrade. For those of you with a Core i7 920 or 940, are you anxious to see how far you can take it?

Dell Tempts with the XPS 435

Posted by Hooch Tan in "Digital Home News" @ 07:00 PM

"The XPS 435 can be found on Dell's website, a quick glance at the specs shows that it is indeed a top of the line PC: Core i7 Extreme, powerful graphics, optional Blu-Ray drive, up to 24GB of RAM and up to 4.5TB of hard drive space makes it a powerhouse."

I can accept the choice of the Core i7 Extreme; it's just about the fastest thing out there short of using liquid nitrogen. I can see someone using 4.5TB of hard drive space as my own storage farm is close to the same. A slick Radeon HD4870 GPU is also a good choice and it'll even handle Crysis, mostly. But I'm trying to wrap my head around why someone, short of server uses or editing really, really high resolution photos, would need 24GB of RAM. But this is supposed to be Dell's premium, top of the line, showcase PC, so why not? It looks slick, and has some thoughtful features like a set of three USB ports, media card reader and inset tray on top of the case for easy access. The only thing they haven't shown is the princely sum you'll need to pay for a computer that can probably run more than 6 copies of World of Warcraft at the same time.

Core i7 Overclocking Examined

Posted by Hooch Tan in "Digital Home News" @ 08:30 PM

"The bulk of overclockers, however, are more concerned with the cost dividends. If you can take a $300 CPU and make it as fast or faster than one that costs $1,000, the money you save can go toward other components in your system. For these folks, it’s like getting a free high-end videocard. Whether you’re a cheapskate or a drag racer, you’ll find that Intel’s new Core i7 CPU is unlike any previous Intel CPU, and overclocking this beast requires more tinkering than you might expect. Follow along as we explore what it takes to push this chip hard."

It seems as if Intel goes through phases when it comes to being overclock friendly. Every few generations, Intel releases CPUs that can be insanely overclocked like the Core 2 Duo, or, and I'm dating myself a bit, the original Celeron. Then they realize they're cannibalizing their premium CPU sales and lock things down. That seems to be the case with the Core i7 series, where the low cost 920 needs work to speed it up while the 965 Extreme Edition is easier to boost. I do find it interesting that AMD is on the flip side with the recent release of the Phenom II which has proven to be very overclocking friendly. Should you be bitten by the speed bug, just be aware that you are going to need more than that stock cooler to keep things running reliably. While the investment may pay off, you could compromise stability, and possibly even your warranty.
