In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 6870 IceQ X Edition are significantly better than the Nvidia GeForce GTX 745 (OEM).

The GTX 745 has a 133 MHz higher core clock speed than the HD 6870, but the HD 6870 has 24 more Texture Mapping Units than the GTX 745. As a result, the HD 6870 exhibits a 17.3 GTexel/s better Texture Fill Rate than the GTX 745. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GTX 745 has a 133 MHz higher core clock speed than the HD 6870, but the HD 6870 has 16 more Render Output Units than the GTX 745. As a result, the HD 6870 exhibits a 12.3 GPixel/s better Pixel Fill Rate than the GTX 745. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GTX 745 was released over a year more recently than the HD 6870, and so the GTX 745 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the HD 6870.

The GTX 745 has 3072 MB more video memory than the HD 6870, so is likely to be much better at displaying game textures at higher resolutions. However, overall, the HD 6870 has superior memory performance.

The HD 6870 has 105.6 GB/sec greater memory bandwidth than the GTX 745, which means that the memory performance of the HD 6870 is massively better than the GTX 745.

The GeForce GTX 745 (OEM) has 384 Shader Processing Units and the Radeon HD 6870 IceQ X Edition has 1120. However, the actual shader performance of the GTX 745 is 536 and the actual shader performance of the HD 6870 is 504. The GTX 745 having 32 better shader performance is not particularly notable, as altogether the HD 6870 performs better when taking into account other relevant data.

The GTX 745 transistor size technology is 12 nm (nanometers) smaller than the HD 6870. This means that the GTX 745 is expected to run slightly cooler and achieve higher clock frequencies than the HD 6870.

The GeForce GTX 745 (OEM) requires 55 Watts to run but there is no entry for the Radeon HD 6870 IceQ X Edition. We would recommend a PSU with at least 300 Watts for the GTX 745 and a PSU with at least 500 Watts for the HD 6870. The HD 6870 has been recommended a PSU with 200 Watts more than the GTX 745. The difference is significant enough that the HD 6870 may have an adverse affect on your yearly electricity bills in comparison to the GTX 745.

GPU Mini Review

Mini ReviewOverview
GeForce GTX 745 is an OEM only, Fast-Middle-Class Graphics Card based on the First Variant of the Maxwell architecture.

Architecture
The first variant of the Maxwell Architecture succeeds the Kepler Architecture. Despite being also manufactured with a 28nm technology, it has an extremely large L2 Cache which allows NVIDIA to produce Graphics Cards with relatively small memory data transfer rates, without causing too much impact on the overall performance. Furthermore, the Shaders have been redesigned and are both more powerful and energy efficient.

GPU
It equips a GPU codenamed GM107-300-A2 which has 3 SM activated and thus offers 384 Shader Processing Units, 24 TMUs and 16 ROPs, on a 128-bit memory interface of DDR3. The central unit runs at 1033MHz.

Memory
The GPU accesses a 4GB frame buffer of DDR3, through a 128-bit memory interface. The size of the frame buffer is exaggerated and in no way benefits the GPU. The Memory Clock Operates at 900MHz.

Features
DirectX 11.2 Support (11.0 Hardware Default) and support for GameStream, G-SYNC, GPU Boost 2.0, GeForce Experience, PhysX and other technologies.

Power Consumption
With a rated board TDP of 55W, it requires at least a 300W PSU and relies entirely on the PCI Slot for power.

Performance
Benchmarks Indicate Good Performance at resolutions up to 1920x1080.
However, even at 1920x1080 GeForce GTX 750 is still considerably faster.

System Suggestions
We recommend a considerably strong processor (Intel Core i3 Dual Core/AMD FX Quad Core) and 8GB of RAM for a system with GeForce GTX 745.
Radeon HD 6870 IceQ X Edition is a special edition of the high-end Radeon HD 6870. See its page for more information about it.
Compared to the Radeon HD 6870, this Special Edition has exactly the same specifications and the only new feature is an improved cooling system which doesn't affect performance directly.
Therefore, the performance is EXACTLY like the standard Radeon HD 6870 and enough to run today's demanding games at maximum settings while Very Demanding games like Metro 2033 or Max Payne 3, will probably require reduced settings to run smoothly.
