Note - Before we start the game benchmarks we need to mention the following - we are currently revising the game test suite and hardware involved - we have removed the Radeon HD 5870 from the suite and have switched to the GeForce GTX 580. Starting in 2011 we'll also switch from 4 GB memory to 8 GB system memory. As a result we can't use older game results any longer and thus very little comparative material is to be found for the moment. Over time the results will build up again. We have chosen the GTX 580 as it is currently the fastest single GPU based graphics card on the globe, excellent for demonstrating CPU versus GPU changes - and CPU bottlenecks.
Far Cry 2
Throw your memory back to the year 2004 and the release of the innovative Far Cry on the PC. Developer Crytek managed to fashion one of the most convincing and striking locales in all of gaming, and satisfied gamers with the freedom to pass through the landscape and tackle enemies in almost any way they saw fit. You surely remember Jack Carver and that things were about to get seriously messed up for you? Well, tough luck. You are no longer at that deserted tropical island but hop into a jeep and arrive at the sandy savannah surroundings of Africa. And that's a change... as much as you'll no longer run into any mutants, aliens, or any superpowers or psychic powers. Also - you are no longer Jack Carver, you assume the role of one of nine different mercenaries who are embedded in the midst of a brutal civil war which rages in an imaginary African nation.
Everything that goes down is involved in a dirty little bush war in central Africa and you'll have to use a rusty AK-47 and whatever bits of scavenged land mine you can duct-tape together. Two factions struggle for supremacy: the United Front for Liberation and Labour and the Alliance for Popular Resistance, and both are known for blood and control.
We are in high-quality DX10 mode with 4x AA (anti-aliasing) and 16x AF (anisotropic filtering), just look at that performance take off.
Far Cry is not that GPU demanding anymore these days with modern graphics cards and thus is sensitive to CPU changes, especially per CPU core performance starts to really matter. As you can see. Once we overclock to 4300 MHz we again added a decent chunk of performance, up-to 1600x1200 though as then the GPU slowly starts to become the limiting factor.
Now look at that, Far Cry is CPU sensitive as the GPU has a lot of overhead here, per-core performance differences will show massively. And that's what you are looking at. AMD's latest six-core Phenom II X6 1100T (3.7 GHz Turbo Core / 3.3 GHz base) simply gets p0wned by Sandy Bridge. If you were to create a GPU with infinite performance, then the overall performance difference in-between the Phenom II X6 1100T and Core i7 2600K processors would close in at 2x.
But that's not a realistic real-world fact, even a GeForce GTX 580 will be the dominant, limiting and decisive factor with modern games -- let's have a look at that with the next game title.
We review the Core i5 3570K Ivy bridge processor. Will Ivy Bridge be the processor series everything you expected? Go find out in this extensive review here at Guru3D.
Core i5 2500K and Core i7 2600K review
Today we test and review Sandy Bridge, the Intel Core i7-2600K and Intel Core i5-2500K processors. We will pair the 2600K processor with the Intel Desktop Motherboard DP67BG and also run a test with the Intel Core i5-2500K processor on a Intel DH67BL motherboard
Core i5 655K and Core i7 875K processor review
Intel today releases two new processors targeted at a somewhat more enthusiast audience. Yes, processors for tweakers and overclockers. On socket LGA 1156 Intel now releases two K series processors. The 32nm Intel Core i5-655K processor has the very same specifications as the Core i5 650; it will operate at 3.2 GHz, will feature two cores with Hyper-Threading technology, sport 4MB of L3 cache and will be made using 32nm process technology. The difference between the 650 and 655K is the unlocked multiplier only. Then we have the enthusiast class Intel Core i7-875K processor, it has the very same specifications as the Core i7 870; it will operate at 2.93GHz, will feature four cores with Hyper-Threading technology, sport 8MB of L3 cache and will be made using 45nm process technology. The only difference between the two central processing units (CPUs) will be the unlocked multiplier on the 875K chip, which will allow overclockers and enthusiasts to easily boost clock-speed of the product without the necessity of overclocking other parts of their systems.
Core i5 650 - 660 and 661 processor review
The time has come for Intel to debut a new line of mainstream 32nm processors, which we have all learned to recognize under the codename 'Clarkdale', the new CPUs will be aimed at the mainstream desktop PC segment and will complement the chip maker's Core i3 and Core i5 line of products. The Intel processor lineup will include the Core i3 530 and 540 models, as well as the Core i5 650, 660, 661, and 670, which will be featured with Hyper-Threading, 4MB of L3 cache and support for dual-channel DDR3-1333 memory. Well, that and an integrated GPU as well of course. Guru3D will put the Core i5 650, 660 and 661 to the test.
