Intel's new Sandy Bridge CPUs
Intel just announced their new CPUs and several enthusiast web sites have published pre-release reviews. I'm not sure when these are going to be available from vendors, but it looks like soon, and there will be an update to some of the workstation configurations.
A few quick notes:
All these CPUs will require a new motherboard. They use a new socket type, 1155, that is Sandy Bridge's answer to the 1156 socket used by i3, i5 and some i7 desktop CPUs. This isn't Intel trying to sell you more stuff - there were a number of chipset updates required, so the P55 and H55 motherboards wouldn't have worked anyway.
This round of CPUs will fit into the midrange and high-midrange market segments. The high-end is still held by Intel's two 6-core i7 chips for the 1366 platform. These won't be supplanted until Intel releases a new high-end motherboard and 8-core CPUs, several months from now.
The Midrange and Photoshopper builds, and probably the Budget, are going to need to be replaced. The i7-2600K beats the AMD 1100T in multithreaded rendering (but is about 30%, plus or minus, slower than the i7-980X in the December High End config) and runs Photoshop CS5 faster than... well, anything. It does all this while using less power.
The Core i5-2500K is also a heck of a bargain at around $200, with performance around what a current model $300 i7 will give you and a lot of overclocking potential (see below).
The CUDA boxes will not need to be updated. There are currently two chipsets supporting Sandy Bridge CPUs, the H67 and the P67. The H67 supports onboard video and allows one PCIE x16 card. The P67 does not support onboard video and allows one x16 or two x8 cards. This is not sufficient for multiple video cards running CUDA. (But I don't recommend CUDA for most users anyway.)
Intel's built up hopes for integrated GPUs. Enthusiasts were skeptical. Enthusiasts were right. To make benchmark comparisons a real competition, web sites had to dig up video cards like the Radeon 5450, which is so slow it didn't make the cut for the Intern box.
Oh, and by the way, overclockers. They've gone and changed everything for you. See, with the last few generations, most CPUs have locked multipliers but unlocked BCLK. With the new generation, BCLK is almost completely immobile - if the CPU wants 100MHz, you can get 103 if you're lucky. Overclocking requires multiplier adjustment.
Sandy Bridge CPUs without Turbo Boost have a fully locked multiplier, so what the box says is what you get. CPUs with Turbo have a semi-unlocked multiplier: you can increase it by up to the number of its best Turbo mode.
K series Sandy Bridge CPUs have fully unlocked multipliers, and testers have reported results that are just a bit nuts, like getting a 3.4GHz chip to 4.4GHz with the Intel stock cooler. (Please don't try this at home.)

Compare with cinebench R11.5 , which is similar to 3dsmax realworld render .(With 3dsmax the AMD 6 cores still a little scale up )

--> I7 2600k / AMD 1100T = 6.83/5.84 ~ 1.17 --> 17% faster .
The most impressive thing is the Sandy Bridge CPU using less power.
A few sites are reporting similar results, and the price difference isn't going to be a lot, so I expect that the Midrange is going to be updated to the 2600K, and probably the Photoshopper as well (because the 2600K also looks like the best performer in fewer threads). This launch makes several CPUs obsolete. I'm waiting and seeing what looks best for the Budget.
Ofcause , the Intel I7 2600K will outperform the AMD 1100T with every apps (but 30% faster with multithread render is unfair) . Intel I7 2600K seem to be the best choice for Midrange ... Unless the next AMD Bulldozer make a big chance. Let's wait for it .
Oh, I see. I should have been clearer. The 30% I referred to was a comparison between a theoretical i7-2600K box and the current version of the 3DATSTech High End config, which is an i7-980X.
