Gaming Performance Comparison
In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7970 are very slightly better than the Nvidia GeForce GTX 760.
The GeForce GTX 760 has a 55 MHz higher core clock speed than the Radeon HD 7970, but the Radeon HD 7970 has 32 more Texture Mapping Units than the GeForce GTX 760. As a result, the Radeon HD 7970 exhibits a 24.3 GTexel/s better Texture Fill Rate than the GeForce GTX 760. 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 760 has a 55 MHz higher core clock speed than the Radeon HD 7970 and the same number of Render Output Units. This results in the GeForce GTX 760 providing 1.8 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 GeForce GTX 760 was released over a year more recently than the Radeon HD 7970, and so the GeForce GTX 760 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the Radeon HD 7970.
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 Radeon HD 7970 has 1024 MB more video memory than the GeForce GTX 760, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the Radeon HD 7970 also has superior memory performance overall.
The Radeon HD 7970 has 71.7 GB/sec greater memory bandwidth than the GeForce GTX 760, which means that the memory performance of the Radeon HD 7970 is much better than the GeForce GTX 760.
The GeForce GTX 760 has 1152 Shader Processing Units and the Radeon HD 7970 has 2048. However, the actual shader performance of the GeForce GTX 760 is 1189 and the actual shader performance of the Radeon HD 7970 is 1610. The Radeon HD 7970 having 421 better shader performance and an altogether better performance when taking into account other relevant data means that the Radeon HD 7970 delivers a massively smoother and more efficient experience when processing graphical data than the GeForce GTX 760.
The GeForce GTX 760 requires 170 Watts to run and the Radeon HD 7970 requires 250 Watts. We would recommend a PSU with at least 500 Watts for the GeForce GTX 760 and a PSU with at least 600 Watts for the Radeon HD 7970. The Radeon HD 7970 requires 80 Watts more than the GeForce GTX 760 to run. The difference is significant enough that the Radeon HD 7970 may have an adverse affect on your yearly electricity bills in comparison to the GeForce GTX 760.
|Mini Review||GeForce GTX 760 is a mainstream Graphics Card based on the 28nm, Kepler architecture. |
It packs a Kepler GK104 Core and therefore offer 1152 Shader Processing Units, 96 TMUs and 32 ROPs on a 256-bit memory interface of fast GDDR5. While its central unit runs at 980MHz and goes up to 1032MHz, in Turbo Mode, the memory clock operates at 1502MHz. It draws up to 170W.
Benchmarks indicate its performance is superior to GeForce GTX 660 Ti and just a little beneath GeForce GTX 670.
Suited for a 1080p resolution, most modern games will run at the highest settings while extremely demanding games, such as Crysis 3 & Metro Last Light will require a more modest preset to be played optimally.
Radeon HD 7970 is a High-End Graphics Card based on the Graphics Core Next (GCN) Architecture.
The GCN Architecture succeeds the 40nm Terascale Architecture. In addition to being produced with a 28nm Technology, the GCN Architecture adds other Technologies that allow for energy efficiency. For example, ZeroCore Power, a long idle power saving technology, allows the Graphics Cards to shut down by itself when the Monitor is turned off.
GCN also adds Improved Anisotropic Filtering, DirectX 11 Tessellation and the Partially Resident Textures (PRT) Technology, which enables future games to utilize ultra-high resolution textures with the same performance as today's small and often repetitive textures.
It equips a GPU Codenamed Tahiti XT which has 32 Compute Units activated and thus offers 2048 Shader Processing Units, 128 TMUs and 32 ROPs. The Central Unit is clocked at 925MHz.
The GPU accesses a 3GB frame buffer of fast GDDR5, through a 384-bit memory interface. The size of the frame buffer is exaggerated and in no way benefits the GPU. The Memory Clock Operates at 1375MHz.
With a rated board TDP of 275W, it requires at least a 600W PSU with one available 6-pin and one available 8-pin connectors.
Radeon HD 7950 used to compete with GeForce GTX 680 but its performance was even behind the lower positioned GeForce GTX 670 and was later replaced by a faster Radeon HD 7970 GHz Edition.
Radeon HD 7970 is best suited for resolutions up to and including 1920x1080. We recommend a Strong Processor (Intel Core i5 Quad Core/AMD FX Six Core) and 8GB of RAM for Optimal Performance.
