In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7950 VTX3D 3GB Boost X-Edition are massively better than the Nvidia GeForce GT 740 v3.

The GT 740 has a 126 MHz higher core clock speed than the HD 7950, but the HD 7950 has 80 more Texture Mapping Units than the GT 740. As a result, the HD 7950 exhibits a 66.4 GTexel/s better Texture Fill Rate than the GT 740. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GT 740 has a 126 MHz higher core clock speed than the HD 7950, but the HD 7950 has 16 more Render Output Units than the GT 740. As a result, the HD 7950 exhibits a 12.1 GPixel/s better Pixel Fill Rate than the GT 740. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GT 740 was released over a year more recently than the HD 7950, and so the GT 740 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the HD 7950.

The HD 7950 has 2048 MB more video memory than the GT 740, 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 160 GB/sec greater memory bandwidth than the GT 740, which means that the memory performance of the HD 7950 is massively better than the GT 740.

The GeForce GT 740 v3 has 384 Shader Processing Units and the Radeon HD 7950 VTX3D 3GB Boost X-Edition has 1792. However, the actual shader performance of the GT 740 is 386 and the actual shader performance of the HD 7950 is 1417. The HD 7950 having 1031 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 7950 delivers a massively smoother and more efficient experience when processing graphical data than the GT 740.

The GeForce GT 740 v3 requires 64 Watts to run but there is no entry for the Radeon HD 7950 VTX3D 3GB Boost X-Edition. We would recommend a PSU with at least 400 Watts for the GT 740 and a PSU with at least 500 Watts for the HD 7950. The HD 7950 has been recommended a PSU with 100 Watts more than the GT 740. The difference is significant enough that the HD 7950 may have an adverse affect on your yearly electricity bills in comparison to the GT 740.

GPU Mini Review

Mini ReviewOverview
GeForce GT 740 v3 is an, OEM Only, Middle-Class 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 GK106 which has 2 Stream Multiprocessors activated and thus offers 384 Shader Processing Units, 32 TMUs and 16 ROPs. The Central Unit is clocked at 993MHz.

The GPU accesses a 1GB frame buffer of fast GDDR5, through a 128-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 1250MHz.

Power Consumption
With a rated board TDP of 64W, it requires at least a 400W PSU and it relies entirely on the PCI Slot for power, meaning no extra connectors are required.

GeForce GT 740 v3 is essentially a slower GeForce GTX 650.
Its Performance is identical to the older GeForce GTX 650.

System Suggestions
GeForce GT 740 v3 is best suited for resolutions up to and including 1600x900. We recommend a Performance Processor and 8GB of RAM for Optimal Performance.
Radeon 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.
