Description

Yeah I rigged up my test benches with dual GTX 590s to remove any and all video card bottlenecks (in theory, but instead I just introduced driver limitation bottlenecks). There's always so much debate about this, so I took two similarly priced CPUs and put them head to head in games!

The video sets up a head-to-head CPU gaming showdown between the Intel Core i5-2500K and the AMD Phenom II X6? Wait, accurately, the 1100T, on a quad-SLI platform using two GTX 590s. Linus explains that both CPUs are priced to be competitive and that the test aims to determine which platform delivers better gaming performance at 2560x600 with a heavy GPU configuration. The test bench uses an AMD based 1100T on a 990FX Crosshair V Formula board paired with two GTX 590s, while the Intel side uses a Z68 motherboard with the 2500K and a similar GPU setup, ensuring the comparison focuses on CPU influence rather than GPU bottlenecks. He notes that there are driver and platform caveats, including the decision to disable onboard graphics to avoid confounding results and to focus on CPU-driven frames per second in gaming scenarios. The presenter also details the game settings, such as anti-aliasing adjustments and specific scene presets in titles like Dirt 3, Crisis 2, Witcher 2, and Fear 3, to create a fair and demanding test environment. Throughout, the goal is to measure true gaming performance differences when the CPUs are paired with a high-end multi-GPU setup, rather than relying on typical synthetic benchmarks. The initial results show notable variances across titles, with some titles favoring one CPU over the other, illustrating that real-world performance can be highly game dependent. Concluding the segment, Linus announces that Crisis 2 appears to result in a tie, and he emphasizes that driver and platform nuances can significantly influence outcomes, suggesting that enthusiasts should consider multiple titles when evaluating CPU choice for gaming. He then teases further coverage and encourages viewers to subscribe for more hardware testing content.

Questions answered

Which CPU provided better gaming performance in the tested titles, the 2500K or the 1100T on Quad SLI?
In the majority of tested titles, the 2500K showed superior or comparable gaming performance to the 1100T when paired with Quad SLI, with notable gains in Dirt 3 around 12.5% and Crisis 2 around 35-40% in favor of the 2500K, while some titles like Fear 3 showed driver-related inconsistencies that could affect results.
What were the main testing conditions Linus used to ensure a fair CPU comparison?
Linus used two systems with similar GPU configurations (Quad SLI with GTX 590s) and disabled onboard graphics on the Intel platform to prevent GPU-CPU interaction artifacts. He ran at 2560x600 with controlled settings across multiple titles, and re-tested some titles to verify results, noting driver and platform nuances that can influence outcomes.
