In terms of overall gaming performance, the graphical capabilities of the Intel 645 GT3e are noticeably better than the Nvidia GeForce 940MX 2GB.
The GeForce 940MX 2GB has a 822 MHz higher core clock speed and the same number of Texture Mapping Units as the 645 GT3e. This results in the GeForce 940MX 2GB providing 19.7 GTexel/s better texturing performance. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.
The GeForce 940MX 2GB has a 822 MHz higher core clock speed and 5 more Render Output Units than the 645 GT3e. This results in the GeForce 940MX 2GB providing 8.1 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 645 GT3e was released over three years more recently than the GeForce 940MX 2GB, and so the 645 GT3e is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the GeForce 940MX 2GB when running the latest games.
The GeForce 940MX 2GB has 2048 MB video memory, but the 645 GT3e does not have an entry, so the two GPUs cannot be reliably compared in this area.
Both the 645 GT3e and the GeForce 940MX 2GB have 384 Shader Processing Units. While the two GPUs have the same number of SPUs, the actual performance delivered by the GeForce 940MX 2GB is 644 and by the 645 GT3e is 644. Knowing that the shader performance of the GeForce 940MX 2GB is superior, it is not necessary to examine the GPUs' respective Texture and Pixel Fill Rates.
The 645 GT3e transistor size technology is 14 nm (nanometers) smaller than the GeForce 940MX 2GB. This means that the 645 GT3e is expected to run slightly cooler and achieve higher clock frequencies than the GeForce 940MX 2GB.
The 645 GT3e requires 15 Watts to run and the GeForce 940MX 2GB requires 25 Watts. The GeForce 940MX 2GB requires 10 Watts more than the 645 GT3e to run. The difference is not significant enough for the GeForce 940MX 2GB to have a noticeably larger impact on your yearly electricity bills than the 645 GT3e.

| Mini Review | Overview Intel Iris Plus Graphics 645 GT3e are integrated graphics in some of Intel's Kaby Lake mobile processors. It can be found in Intel Core i5-8257U and the Intel Core i5-8557U Architecture The Kaby Lake architecture succeeds the Skylake architecture and aims for increased CPU and graphics performance, via the same power requirements. It includes support for DirectX 12.1, OpenCL 2.1 and OpenGL 4.6. GPU The central unit initially runs at 300MHz and goes up to 1150MHz, in turbo mode in the Intel Core i5-8557U. Performance Because Performance depends heavily on the Memory Bandwidth, it may vary heavily from System to System. Best case scenario, expect performance identical to a dedicated AMd HD 6790. | Overview GeForce 940MX 2GB is a Middle-Class Mobile Graphics Card based on the Maxwell Architecture. Architecture GeForce 940MX 2GB Features a GPU Codenamed GM108-N16S-GTR which is a First Gen Maxwell GPU and is identical to the GM108-N16S-GT-S used on GeForce 940M but with the addition of GDDR5 Support. GM108-N16S-GTR has 3 Compute Units Unlocked and thus offers 384 Shader Processing Units, 24 TMUs and 8 ROPs. GPU The Central Unit is Clocked at 1122Hz and goes up to 1242MHz, in Turbo Mode. Memory: Speed The GPU is equipped with DDR3 and Accesses the Frame Buffer through a 64-bit Memory Interface. The Memory Clock Operates at 1001MHz. Memory: Frame Buffer The GPU can fill up a Memory Pool of up to 2GB. Power Consumption With a rated board TDP of 25W, it is suited for small and medium sized laptops. Performance Equipped with DDR3, GeForce GT 940MX is only slightly faster than GeForce GT 940M. System Suggestions GeForce 940MX 2GB is best suited for resolutions up to and including 1366x768. We Recommend a Middle-Class Processor and 8GB of RAM for Optimal Performance. | |||
