Seems evident that upgrading to SB from i7 will bring close to no improvement in gaming experience core for core. Other things though, encoding, etc its a fine upgrade. Plus the power consumption is awesome.

Did you see COD black ops and Starcraft 2? On cpu limited games it seems to make a decent difference. Multi-threaded games like BFBC2 see no advantage. If this review is close to accurate SB looks good other than the garbage no bclocking deal.

[informal]

Interesting results. Looks like great improvement in power draw and a much less impressive improvement in IPC(i skimmed over the numbers,it goes from 0 to 25%,mostly hovers under or near 10%;on average ~7% improvement,solid but not impressive). I guess AVX will change things a bit,but we will have to wait for the optimized software.
Why haven't they tested the iGPU or am I missing it somewhere?

I don't know though... 16x10 res with GTX580 :|

I wish they compared it to other processors as well like the 1366 CPU's. Meh, 1155 doesn't really look like an upgrade for X58 970/980x users.

[Chri$ch]

LoL.

970 and 980X are HexaCores and the X58 is High-End and P67 (or LGA1155) is Mainstream with QuadCores.

Single threaded games are dying out a painful death
But yes IPC has improved substantially (for gaming).

That would be a downgrade for 970/980x.
Upcoming SB is not high-end, and won't compete with 6C/12T 32nm CPUs. It will be interesting to see if it can affect the price on these. But these numbers (specially the power usage/heat) shows that it will make sure that all 45nm become antic soon.

but think, they tested without activ turbo2.0, right?

[delasneo]

They 've already active turbo boost 2.0 see the Starcrat 2 and the test turbo 2.0

[kl0012]

I wonder what cpu they have tested. I thought CPU-Z is already able to detect SB correctly.

Any way, 2.8GHz is not a native freq of i7-2600K so I don't sure what turbo they tested exactly.

[haylui]

from earlier leak, the IPC is about 10% increase clock to clock. But what is interesting about Sandy Bridge is AVX and power consumption.

they use a sample what never hit the retail market, its same as the from coolaler (2.8GHz unlocked).

so they overclocked it to 3.4GHz and say its a 2600K

[FlanK3r]

but..clocks to clocks is not big diference (without turbo), whats great is power consum. in load ! Awesome.

[Chri$ch]

yeah, but if they used the voltage as in the CPU-Z screen showed (1.32v) then is the measurement incorrect.

[ajaidev]

I had told you all about how important power saving and turbo will be on SNB long time back the IPC improvement what ever it formulates to is less important i was told that IPC is less important and Intel wanted to use combination of Turbo power saving and the process manufacturing to attract the costumers, i did not expect anything over 5-7% improvement in IPC from 1156 to 1155.

[Manicdan]

shockingly the ipc gains were not much at all

and the turbo tests showed almost no difference (SC2 should have seen much more than just 4.3%)

and power consumption is hard to compare due to the fact they compared it while overclocked, against another overclock. and they didnt mention if they had to adjust voltages or not on the 875K, which would make a massive difference. just going by the charts 229W - 89W = 140W difference between idle and load. so did they really have to make the 875K a 170W TDP cpu just to reach 3.4ghz?

[Rebel44]

Nice, but I would prefer more info about S2011 CPUs.

[geo]

Anand's review showed much better improvement that what this review is showing. didn't overclocked 2400k in Annad's review almost match the i980x ?


if this review is true, then there hope for bulldozer

[Metroid]

I guess AVX will change things a bit,but we will have to wait for the optimized software.

This is exactly what I was about to tell. Well instructions are limited to some extent but surely AVX implementation will increase performance.

[Dimitriman]

Thats still a long way away mate..

[flopper]

it depends on how the K model overclocks.
5ghz reachable or close by, well then its a given.

On air 24/7 might be hard to reach that, my prediction stays at 4.5GHz for majority of 2600K users.

[Manicdan]

do we know the max speed for the non K models yet?
