[citation][nom]tpi2007[/nom]2. AMD is in deep trouble. I have a Q9550 at stock (and these E0 overclock very well, to Core i5 750 levels on stock voltage), and it was a bit embarrassing to see their flagship 970 at 3.5 Ghz be the next in line in the graphs. This just proves that the current Quad Core line from AMD is really only competing on price, because architecturally they are on par with the Core 2 Quads @ 45nm. Intel just stopped producing any faster variants and moved on, while AMD is still there, two years late, producing higher clocked versions. If I overclock my Q9550 to 3.5 Ghz I will probably have equal or better performance. As I said, it's embarrassing even to me, let alone for AMD, to see it laid out bare in the graphs. At current prices, AMD's best quad-core line is essentially dead. I hope they come up with something soon though. Only people already on an AMD board will consider these if the price doesn't change soon.[/citation]

I beg to differ, my friend. AMD might not have a clock per clock win, but their P/P ratio IS good. A Phenom II X4 955 c3 stepping can run @4Ghz with no sweat, and there is when it triumphs over Core i5 on this gen. I have a 965 c3 (cause there were no 955 c3) running @3.9Ghz on a 890FX MoBo (wasn't lucky to get stable @4Ghz). I can tell you it beats any C2D (have a friend running one @3.8Ghz and I beat him on benchies and gaming, thanks to the IMC and bigger PCIe bandwith is my guess). Even more, if you would like to play "risky", you could get a Phenom II X2 555 and unlock it to get a free 955, so I really think AMD ain't lost at ALL in the P/P battle. Maybe clock for clock and efficiency, but not pure P/P; they still game on that area (they must or they'd really be dead =/ ). Even more when you add MoBo's into the mix and all the goodies you get for your buck.

[citation][nom]tpi2007[/nom]3. For the price, I predict the i5-2500k is going to be a best-seller. Only 11$ more expensive than the non-k version and excellent performance with unlocked multiplier; another best-seller for those who want 4 cores, the best performance and save the maximum amount of cash is the i5-2400. 300Mhz base clock faster than the 2300 for only seven bucks more, when the difference upwards is only 200Mhz and 100Mhz and with bigger price differences. Overall, it's a very welcome nice step up, and I do understand their strategy for overclocking, it might upset those super-value seekers, but hey, unlocked processors just got a lot cheaper, right ? I think the disadvantages are clearly outnumbered by the advantages, and still more platforms to come which allow more overclocking. My only gripe is with QuickSync for the reasons I stated above, I hope it's just a software problem, otherwise it is useless to many, many people.[/citation]

I have a little objection there. It's not "unlocked" (from what I undertand), it's only a little feature they give you so they can charge you more instead of getting it from factory and/or tweaking it yourself. They could charge you full price for that little headroom without having to do much more than not using the lock; a gimmick if you like to get a cheap shot at your wallet. I just hope ASUS and friends get some sort of cheap unlock/bypass like in the P4 Presshots era. And, you can't have both of the best worlds; I need more info on this one, but MoBos equipped with the H67 won't be aimed for the upper-mid segment, right? So bye bye real value; graphics switching on the Desktop should be considered too... With all the energy going to discrete graphics these days, a little save here and there could make a difference IMO.

Still, I can't ignore mere performance; they ARE fast. Hellish fast. Intel did a great job on that department. Hope AMD takes note on the bad things from SB and make a better product. Don't care if it's perf' king, just make it go fast and make it P/P king. Let me keep my rig over 60FPS with v-sync on and make more devs use APP/CUDA. I don't want to lose another "3DNow" thanks to "Evil" wrong doings.

Cheers!

The Quick Sync thing is IMHO the most impressive part. I have to wonder if AMD has a similar thing in mid for Bulldozer... esp. given that AMD has had better GPU tech than Intel. I sure hope I do not see a foot-bullet with serial number 'AMD' when BD hits the market!
 
[citation][nom]greghome[/nom]AMD's Answer ?Fusion.................:lol:just hope it's not gonna be a fluke or even worse.....a failure[/citation]

Unless Fusion employs something similar to Quick Sync, I doubt it will be any better than a HD6870 in the benchmarks.

I have to say that Intel really upped their game with Sandy Bridges IGP. It not only provides discrete entry level gaming abilities (playing L4D2 at 1680x1050 and doing it above 30FPS is quite good) but it can encode and encode video very well.

And the mobile parts will all be the high end version so that will really be something to fight for AMD.

I am seriously concerned for AMDs future. I want AMD to do well, to grab a little more market share, from Intel. Stronger products and stronger competition in the CPU space are necessary to keep getting the value to which I feel I am now accustomed...

But I'm a little concerned for AMD. Even against the Core i- series, AMD was starting to look a little less that spectacular, but the value made it all good. Enter Sandy Bridge. I have a hard time believing that AMD will be able to make up enough ground to remain relevant in such a short time. Bulldozer will have to be some kind of awesome to match the current core i series, much less Sandy Bridge. I could go buy a current i3 that could beat the socks off my quad core AMD clock for clock, even as the 4 physical cores work on multithreaded loads. I just don't see how AMD can launch their next generation of processors with anything like Sandy Bridge performance, or anything like Sandy Bridge performance. Plus, SB will be at least six months on the market before AMD launchs. I think my concerns for AMD are justified. I hope they prove me wrong and have been keeping their powder dry, spending every waking moment working on something incredible. Unfortunately, it could be too late by then.

AMD, prove me wrong.

Wonderful performance upgrade from the new Intel chips. With so many people mentioning their Q9550s, I'll add that there was a reason I kept my e6750 Conroe for the same reason.

However, the real game changer will be when AMD releases Bulldozer. Until then, unless someone really needs a new platform (CPU + MB) or entire system, there is no reason to buy now. Wait for Intel's supply chain to fill online stores & wait for AMD's new chips to be priced correctly with the existing "new chip - Intel" market.

One thing is for certain though... except for the OEM and business markets, the duel core non-hyperthreaded CPU, for the most part, has now died. And, even the duel core with HT'ing will probably be dead in a year. Software is finally catching up in thread optimization...

[citation][nom]cangelini[/nom]I actually asked that question to Intel this morning. *HUGE* drawback to Quick Sync--it *has* to be used with integrated graphics (added this point to the review itself). It CAN be done with Switchable Graphics on the mobile side, but it's a significant effort. Here's the official response:"For switchable graphics configurations, Intel® Quick Sync Video may remain functional and enabled. This requires the OEM to work with their preferred graphics and software vendor for validation. In addition, Intel Quick Sync Video can work in multi-monitor using multiple graphics device configurations. However, the application must be enabled through the Media SDK and the processor graphics output must be driving a display. In other words, a monitor must be connected to the Intel processor graphics port."This does, in fact, suck. I want to be able to use Quick Sync with my discrete card, because I'm not giving up discrete graphics for fast transcoding. Hope that answers your question!!Best,Chris[/citation]

so we cannot use the integrated GPU as a GPGPU device when it is not driving a display ?

unfortunately QS seems to be only usabel when the integrated GPU is actualy attached to a display. so not very practical at the moment.

Impressive results for transcoding/encoding. We'll have to wait for this architecture to mature before it's a viable option to replace low-end gaming rigs. HTPC and workstation use is definitely reasonable here though. Thanks for the comparison Chris; good information here!

Reading Anandtech's review, I always wondered how CUDA got the numbers so low...now I know that it's because they're cheating. >.< I'd rather spend more time getting a quality video than less time cranking out crap. Wtf nVidia...fail.

[citation][nom]cangelini[/nom]Correct--this would make it very useful on a notebook, and significantly less accessible on a desktop.[/citation]

I wonder why Intel is so stupid. I mean it's just a functional unit in the CPU that's wasted in most times (except notebooks maybe) for any but the cheapest desktops. they waste silicon, die area and power/heat budget with this.

Why can't they just let us use it as a co-processor in case it has no display attached ? Simply output to a framebuffer memory region and you are done.
 
While many of you were enjoying time away from word around Christmas and digging out of blizzard-like conditions ahead of New Year's Eve, the Tom's Hardware Bakersfield, CA lab was kept busy and warm by the latest bleeding-edge CPUs being run through their paces. Shall we?
Think this should be work instead of word.

I would like to see some OC benchmarks with the i7-2600k against the E5620 and E5630. Clock for clock the i7-2600k doesn't look out class generation 1 by much. I've seen OC's of the E5630 over 5GHz which make me question generation 2's claim for the top. Which can OC the highest and can the i7-2600k make up for 4mb less cache?

Is it me? Or have you all stopped rating comments? Very weird!
About the article, all what I can say is: (REALLY!)
I really hated Intel this time, and please don't shoot for this, it's how I see it.
 
Wow, stupid. The K series chips for overclocking are the only ones to feature the better graphics (3000), however no enthusiests overclockers are even going to use int. graphics and to top it off, the H67 that you need to use it on doesn't support overclocking. LOL
How retarded is that???
