NVIDIA GeForce GTS 450 Affordable DX11 GPU

How We Configured Our Test Systems: We tested the graphics cards in this article on a Gigabyte GA-EX58-UD5 motherboard powered by a Core i7 965 quad-core processor and 6GB of OCZ DDR3-1333 RAM. The first thing we did when configuring the test system was enter the system BIOS and set all values to their "optimized" or "high performance" default settings. Then we manually configured the memory timings and disabled any integrated peripherals that wouldn't be put to use. The hard drive was then formatted, and Windows 7 Ultimate x64 was installed. When the installation was complete we fully updated the OS and installed the latest hotfixes, along with the necessary drivers and applications.

Unigine Heaven v2.1 Benchmark
Synthetic DirectX 11 Gaming


Unigine Heaven

The Unigine Heaven Benchmark v2.0 is built around the Unigine game engine. Unigine is a cross-platform real-time 3D engine, with support for DirectX 9, DirectX 10, DirectX 11 and OpenGL. The Heaven benchmark--when run in DX11 mode--also makes comprehensive use of tessellation technology and advanced SSAO (screen-space ambient occlusion), and it also features volumetric cumulonimbus clouds generated by a physically accurate algorithm and a dynamic sky with light scattering. Due to the fact that we tested Heaven in DX11 mode, no NVIDIA GT200 series cards are represented in the graph below.

We have tested a reference GeForce GTS 450 alongside both of the overclocked retail editions. As you can see, even the reference clocked GeForce GTS 450 manages to outpace the Radeon HD 5770 here; the overclocked editions from EVGA and Asus simply extend the lead.
