In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 670 are marginally better than the AMD Radeon HD 7950 VTX3D 3GB Boost X-Edition.

The GeForce GTX 670 has a 35 MHz higher core clock speed and the same number of Texture Mapping Units as the HD 7950. This results in the GeForce GTX 670 providing 3.9 GTexel/s better texturing performance. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GeForce GTX 670 has a 35 MHz higher core clock speed than the HD 7950 and the same number of Render Output Units. This results in the GeForce GTX 670 providing 1.1 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The HD 7950 was released less than a year after the GeForce GTX 670, and so they are likely to have similar driver support for optimizing performance when running the latest games.

Both GPUs exhibit very powerful performance, so it probably isn't worth upgrading from one to the other, as both are capable of running even the most demanding games at the highest settings.

The HD 7950 has 1024 MB more video memory than the GeForce GTX 670, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the HD 7950 also has superior memory performance overall.

The HD 7950 has 47.7 GB/sec greater memory bandwidth than the GeForce GTX 670, which means that the memory performance of the HD 7950 is noticeably better than the GeForce GTX 670.

The Radeon HD 7950 VTX3D 3GB Boost X-Edition has 1792 Shader Processing Units and the GeForce GTX 670 has 1344. However, the actual shader performance of the HD 7950 is 1417 and the actual shader performance of the GeForce GTX 670 is 1317. The HD 7950 having 100 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 7950 delivers a noticeably smoother and more efficient experience when processing graphical data than the GeForce GTX 670.

The GeForce GTX 670 requires 170 Watts to run but there is no entry for the HD 7950. We would recommend a PSU with at least 500 Watts for the HD 7950 and a PSU with at least 500 Watts for the GeForce GTX 670. The two GPUs have been recommended a PSU with the same amount of wattage. As such, there is no need to worry about which will more significantly affect your yearly electricity bills.

GPU Mini Review

Mini ReviewRadeon HD 7950 VTX3D 3GB Boost X-Edition is a special edition of the high-end Radeon HD 7950 Boost Edition.
This edition comes with a custom cooling solution and overclocking out of the box in the core-clock that was increase by 30MHz to 880MHz. Therefore, the Turbo Boost is now of 930MHz.
Expect a 1.5% performance boost when compared to the reference Radeon HD 7950 Boost Edition.
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

Power Consumption
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.

System Suggestions
We recommend a Powerful Processor (Intel Core i5) and 8GB of RAM for a system with GeForce GTX 670.
