Sandy Bridge, this is the codename of Intels latest CPU generation which is based on an overworked Nehalem microarchitecture. We had the chance to test two of the upcoming CPUs, namely the Core i7 2600K and the Core i5 2500K. They both come with an improved graphics core which has been integrated into the same piece of silicium as the CPU itself. Both models we tested are quad core CPUs whereas the Core i7 2600K supports hyperthreading and the Core i5 2500K doesn't. Another difference between the two CPUs is their cache size. Therefore the 2600K which aims more at the high-end market has been equipped with 8 MByte of L3 cache whereas the 2500K only got 6 MByte.

Sandy Bridge CPU / GPU / Overclocking
With Sandy Bridge Intel shows the first major overwork of their Core i7 800 series CPU architecture. The two CPUs we tested aim at the performance desktop segment where they can really show what they're capable of. If you compare Sandy Bridge with Lynnfield you see that the graphics core has now been integrated into the same piece of silicium like the CPU. To make the graphics core profit as much as possible Intel equipped Sandy Bridge with a ring architecture. This enables communication between every single compartment. In plaintext this means that the graphics core can access data which lies in Level 3 Cache. Furthermore even the System Agent can control the graphics core to for example change clock speeds. Furthermore Intel also overworked their TurboBoost technology which now comes in version 2.0. Now TurboBoost is even more flexible and as we already mentioned it can also control the GPUs clock speeds.
If one starts looking for differences between the P67 and P55 Chipset you'll find plenty. Therefore let us start with the DMI link (Direct Media Interface). With the P67 DMI is a 20 Gb/s interface which allows quick communication between the CPU and the chipset itself. Compared to the previous generation the DMI link is now ten times faster. With P67 you also get eight PCI-Express x1 slots instead of six like with the P55. Also the onboard LAN controller has now been connected to the chipset via a PCI-Express x1 lan. Very important for owners of high-end SSDs is that P67 natively comes with up to six SATA3 6Gbps ports.
As we already mentioned with the new core processors Intel integrated the graphics unit into the same piece of silicium like the CPU. Therefore all the new Core CPU don't feature a multi chip package anymore. The differences between HD2000 and HD3000 are mainly between the number of execution units as well as the clock speeds. HD2000 has got six execution units whereas HD3000 has been equipped with twelve. Compared to the older graphics units we find on Lynnfield HD2000 and HD3000 do perform much better. One reason for this is the Level 3 cache which can be accessed directly. Intel itself even goes that far that they say that casual gaming should be possible with HD3000 and HD2000.
Overclocking
It's been a discussion over and over again at Intel wether they should control overclocking or not. With Sandy Bridge Intel decided to limit overclocking via the busclock which only leaves the multiplyer to increase clock speeds. Also the multiplyer can only be changed if you own a K-Series CPU. With the 2600K for example one is able to increase the multiplyer all the up to 57 which means that a maximum of 5'700 MHz would be possible. If we now take into account that on the latest ASUS boards you can achieve a maximum of 107 busclock you end up with 6'099 MHz. Generally Sandy Bridge is entirely different in terms of overclocking which is why we're going to release an article which focuses only on this topic.

3DMark 06
3DMark 06 is getting older these days. Therefore if you are using really powerful graphic cards you will hit CPU limitation which means that the graphic card isn't the bottleneck in the system. This is also the reason why in recent high-end desktop systems 3DMark 06 scales nicely with the CPU and the graphic card has much less influence on the scores.

3DMark Vantage is able to squeeze nearly everything out of a recent system. Therefore the feature liste is also pretty long: DirectX10, FP16-HDR, motion blur, parallax occlusion mapping, GPU-physics simulation and different shader effects are being used to even make recent high-end systems struggle.

Cinebench
The test procedure consists of two main components: The first test sequence is dedicated to the computer's main processor. A 3D scene file is used to render a photoreaslistic image. The scene makes use of various CPU-intensive features such as reflection, ambient occlusion, area lights and procedural shaders. During the first run the benchmark only uses one CPU (or CPU core) to ascertain a reference value. On computers that have multiple CPUs or CPU cores and on those that simulate multiple CPUs (via HyperThreading or similar technolgies), Cinebench will run a second test using all available CPU power.

Crysis DirectX10
Crysis is still one of the games which has very high system requirements. Therefore developer Crytek implemented Direct3D-10-API, High-Dynamic-Range-Rendering, Parallax Occlusion Mapping, Soft Shadows, Motion Blur, Depth of Field as well as Soft Particles. We test Crysis by using DirectX10 to show CPU-sacaling especially which low resolutions. If we look at the high resolutions we are able to spot that the CPUs influence compared to the graphic card becomes much less important.

PT Boats Knights of Seas DirectX10
PT Boats Knights of Seas is based on the Direct-3D-10 API, supports multicore CPUs and comes with a physics engine. Also at this point we see a good scaling of the CPU at low resolutions and nearly no influence when applying high resolutions.

Resident Evil 5 DirectX10
Resident Evil uses nearly every modern rendering technology: HDR, Hemisphere Lighting, Soft Shadows, Soft Particles, Field- und Motion-Blur oder auch Alpha to Coverage and static Ambient Occlusion. Furthermore Resident Evil 5 has been optimized for multicore architectures and already comes DirectX11 ready. By using the DirectX10 benchmark we can again show you CPU-scaling with low resolutions and the compared to the CPU overproportional influence of the graphics card at high resolutions.

Street Fighter4
Street Fighter 4 comes with an extra benchmark version which makes testing you system childrens play. At low resolutions the system requirements are pretty low and we can see CPU-scaling in the results. At high resolution the graphic card becomes more important and the CPUs clock speed has less influence on the fps.

Conclusion
With Sandy Bridge Intel not only shows new CPUs they also introduce their new socket 1155. Furthermore Intel also seems to have overworked the memory controller. With the Core i7 2600K is was possible to run our Kingston memory at 2'133 MHz absolutely stable. As a consequence the system performed better by quite a margin. Generally Intel did a lot regarding efficiency which results in more performance per MHz. Also TurboBoost has been overworked. But this time it was Intels intention to make this feature more flexible that it for example also supports the integrated graphics core.
The new Core i7 2600K as well as the Core i5 2500K almost dominate the quad core CPUs we've tested so far. Therefore the Core i7 2600K can even outperform a Core i7 975XE. Of course looking at memory bandwidth the P67 platform with 1'333 MHz DDR3 memory is slower than the triple channel X58. But on the other hand if you own memory which allow you to set 2'133 MHz Sandy Bridge can even outperform a triple Channel interface. If you're looking for some further evidence that Sandy Bridges performance per MHz has been increased you can look at the SuperPi results. There you can clearly see that Core i7 2600K as well as Core i5 2500K are in another league.
Especially astonishing is the fact that Core i7 2600K as well as Core i5 2500K both are mid range CPUs. Intel recommended USD 317 for the Core i7 2600K and USD 216 for the Core i5 2500K which makes both of these CPUs exceptionally good value for money.
Intels Core i7 2600K as well as Core i5 2500K definitely are upgrades compared to their Lynnfield predecessors. If you should already own memory which can achieve very high clock speeds you'll do everything right in buying a P67 platform. Generally we can recommend Sandy Bridge CPUs equally for HTPCs as well as gaming systems one can even find a Sandy Bridge based CPU which suites an office PCs needs. Therefore the high end market has been the only segment which has not been upgraded with the release of these CPUs. High end can still rely on the Core i7 980X six core CPU.
