GeForce GT 740 v2 is a 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 GK107-425-A2 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.

DirectX 12.0 Support (11.0 Hardware Default) and support for CUDA, OpenCL, DirectCompute, 3D Vision Surround, PhysX, Realtime Raytracing and other technologies

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 v2 is essentially a slower GeForce GTX 650.
Gaming benchmarks indicate its performance is not too far from the older GeForce GTX 650.

System Suggestions
Recommend a modest processor (Intel Core i3) and 8GB of RAM for a system with GeForce GT 740 v2.


GeForce GTX 650 Ti is a fast-middle-class GFX based on the Kepler GK106 Core and successor to previous GeForce GTX 550 Ti.
Based on the Kepler GK106 Core, GeForce GTX 650 Ti features 768 Cuda Cores equipped with fast GDDR5 on a 128-bit memory interface. The Central Clock is set at 928MHz and the memory clock runs at 1350MHz. As everyone knows, the Kepler GK106 offers great overclock-ability so expect to see a lot of variants of GeForce GTX 650 Ti with central clocks of over 1000MHz.
The performance, when compared to previous GeForce GTX 550 Ti is over 30% better, the price is average and benchmarks indicate modern demanding games can be played smoothly at the highest settings while extremely demanding games are playable at high settings with modest resolutions smoothly.
Note: Please beware that GeForce GTX 650 Ti DOES NOT support SLI.


Nvidia GeForce GTX 650 Ti are significantly better than the Nvidia GeForce GT 740 v2
In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 650 Ti are significantly better than the Nvidia GeForce GT 740 v2.

The GT 740 has a 65 MHz higher core clock speed than the GTX 650 Ti, but the GTX 650 Ti has 32 more Texture Mapping Units than the GT 740. As a result, the GTX 650 Ti exhibits a 27.6 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 65 MHz higher core clock speed than the GTX 650 Ti and the same number of Render Output Units. This results in the GT 740 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 GT 740 was released over a year more recently than the GTX 650 Ti, and so the GT 740 is likely to have better driver support, meaning it will be more optimized for running the latest games.

The GeForce GT 740 v2 and the GeForce GTX 650 Ti have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The GTX 650 Ti has 6.4 GB/sec greater memory bandwidth than the GT 740, which means that the memory performance of the GTX 650 Ti is marginally better than the GT 740.

The GeForce GT 740 v2 has 384 Shader Processing Units and the GeForce GTX 650 Ti has 768. However, the actual shader performance of the GT 740 is 381 and the actual shader performance of the GTX 650 Ti is 713. The GTX 650 Ti having 332 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 650 Ti delivers a noticeably smoother and more efficient experience when processing graphical data than the GT 740.

The GeForce GT 740 v2 requires 64 Watts to run and the GeForce GTX 650 Ti requires 110 Watts. We would recommend a PSU with at least 400 Watts for the GT 740 and a PSU with at least 400 Watts for the GTX 650 Ti. The GTX 650 Ti requires 46 Watts more than the GT 740 to run. The difference is significant enough that the GTX 650 Ti may have a slight adverse affect on your yearly electricity bills in comparison to the GT 740.
