GeForce GTX 670 Game Requirement Analysis
GeForce GTX 670 is a High-End Graphics Card based on the first revision of the Kepler Architecture.
The Kepler Architecture was NVIDIA's big step to power efficiency. Each Stream Multiprocessor (SMX) now hosts 192 Shader Processing Units - against the 48 of older Fermi Architecture, and has been redesigned being now clocked at the same speed of the Central Unit. This means they are more energy efficient and will consequently lead to cooler operating temperatures. However, it also means they are weaker. It can be said that one Fermi SMX is as fast as 2 Kepler SMXs.
Additionally, and not available in all GPUs, Kepler also introduced the Boost Clock Feature. The Boost Clock is an even higher Clock Speed activated when in gaming mode and becomes the effective speed of the GPU.
It equips a GPU Codenamed Kepler Kepler GK104-N13E-GTX-A2 which has 7 Stream Multiprocessors activated and thus offers 1344 Shader Processing Units, 112 TMUs and 32 ROPs. The Central Unit is initially clocked at 915MHz and goes up to 980MHz, in Turbo Mode.
The GPU accesses a 2GB frame buffer of fast GDDR5, through a 256-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 1502MHz.
DirectX 11.0 Support (11.0 Hardware Default) and support for SLI, CUDA, OpenCL, DirectCompute, 3D Vision Surround, PhysX, Realtime Raytracing and other technologies
With a rated board TDP of 170W, it requires at least a 500W PSU with two available 6-pin connectors.
With one Streaming MultiProcessor disabled, when compared to the higher positioned GeForce GTX 680, its performance lies somewhere between a Radeon HD 7950 and a Radeon HD 7970. However, at higher resolutions, Radeon HD 7970 is considerably faster.
We recommend a Powerful Processor (Intel Core i5) and 8GB of RAM for a system with GeForce GTX 670.
