Crysis Benchmarks

Crysis uses a new graphics engine: the CryENGINE2, which is the successor to Far Cry's CryENGINE. CryENGINE2 is among the first engines to use the Direct3D 10 (DirectX10) framework of Windows Vista, but can also run using DirectX9, both on Vista and Windows XP.

Roy Taylor, Vice President of Content Relations at NVIDIA, has spoken on the subject of the engine's complexity, stating that Crysis has over a million lines of code, 1GB of texture data, and 85,000 shaders.

To get the most out of modern multicore processor architectures, CPU intensive subsystems of CryENGINE 2 such as physics, networking and sound, have been re-written to support multi-threading.

Crysis offers an in-game benchmark tool, which is similar to World in Conflict. This short test does place some high amounts of stress on a graphics card, since there are so many landscape features rendered. For benchmarking purposes, Crysis can mean trouble as it places a high demand on both GPU and CPU resources. Benchmark Reviews uses the Crysis Benchmark Tool by Mad Boris to test frame rates in batches, which allows the results of many tests to be averaged.


When we tested with World in Conflict, there was a noticeable disadvantage for CrossFireX sets when used on the Gigabyte GA-EP45T-EXTREME when compared to the same set on the GA-X48T-DQ6 X48 motherboard. Things only get more separated with Crysis, as the CrossFireX sets show more of a preference for the full 16 lanes of bandwidth at each end. Dropping both PCI Express 2.0 compliant ports down to 8x, the EP45T-EXTREME P45 motherboard produced results 7-14% below the performance of the same hardware on a 16x + 16x lane configuration.

Aside from CrossFireX multi-card configurations, there's no real difference between the P45 and X48 in terms of single-unit performance. Based on our series of Crysis benchmarks, the test results indicate that the Gigabyte GA-EP45T-EXTREME cannot offer the same level of performance as their GA-X48T-DQ6 in CrossFireX, but both perform the same otherwise.

This concludes our benchmark testing portion, and now we move on to measuring the power consumption of the Gigabyte GA-EP45T-EXTREME and compare it to the others.
