NVIDIA GeForce GT 640: specs and benchmarks
- Interface PCIe 3.0 x16
- Core clock speed 902 MHz
- Max video memory 2 GB
- Memory type DDR3
- Memory clock speed 1782 MHz
- Maximum resolution
NVIDIA started GeForce GT 640 sales 5 June 2012 at a recommended price of $99. This is Kepler architecture desktop card based on 28 nm manufacturing process and primarily aimed at office use. 2 GB of DDR3 memory clocked at 1.78 GHz are supplied, and together with 128 Bit memory interface this creates a bandwidth of 28.51 GB/s.
Compatibility-wise, this is single-slot card attached via PCIe 3.0 x16 interface. Its manufacturer default version has a length of 145 mm. No additional power connector is required, and power consumption is at 65 Watt.
It provides poor gaming and benchmark performance at
of a leader's which is NVIDIA GeForce RTX 3080 Ti.

- 3DMark Fire Strike Graphics
- Octane Render OctaneBench
Fire Strike is a DirectX 11 benchmark for gaming PCs. It features two separate tests displaying a fight between a humanoid and a fiery creature seemingly made of lava. Using 1920x1080 resolution, Fire Strike shows off some realistic enough graphics and is quite taxing on hardware.
This is probably the most ubiquitous benchmark, part of Passmark PerformanceTest suite. It gives the graphics card a thorough evaluation under various load, providing four separate benchmarks for Direct3D versions 9, 10, 11 and 12 (the last being done in 4K resolution if possible), and few more tests engaging DirectCompute capabilities.
This is a special benchmark measuring graphics card performance in OctaneRender, which is a realistic GPU rendering engine by OTOY Inc., available either as a standalone program, or as a plugin for 3DS Max, Cinema 4D and many other apps. It renders four different static scenes, then compares render times with a reference GPU which is currently GeForce GTX 980. This benchmark has nothing to do with gaming and is aimed at professional 3D graphics artists.
Cryptocurrency mining performance of GeForce GT 640. Usually measured in megahashes per second.
|Bitcoin / BTC (SHA256)||24 Mh/s|
Let's see how good GeForce GT 640 is for gaming. Particular gaming benchmark results are measured in frames per second. Comparisons with game system requirements are included, but remember that sometimes official requirements may reflect reality inaccurately.
Overall GeForce GT 640 performance compared to nearest competitors among desktop video cards.
We believe that the nearest equivalent to GeForce GT 640 from AMD is Radeon R7 250, which is nearly equal in speed and is lower by 1 position in our rating.
