In terms of overall gaming performance, the graphical capabilities of the Intel UHD Graphics 630 are marginally better than the Nvidia GeForce GT 640.

The GeForce GT 640 has a 552 MHz higher core clock speed and 9 more Texture Mapping Units than the UHD Graphics 630. This results in the GeForce GT 640 providing 20.8 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 GT 640 has a 552 MHz higher core clock speed and 13 more Render Output Units than the UHD Graphics 630. This results in the GeForce GT 640 providing 13.3 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 UHD Graphics 630 was released over three years more recently than the GeForce GT 640, and so the UHD Graphics 630 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the GeForce GT 640 when running the latest games.

The GeForce GT 640 has 2048 MB video memory, but the UHD Graphics 630 does not have an entry, so the two GPUs cannot be reliably compared in this area.

The UHD Graphics 630 has 184 Shader Processing Units and the GeForce GT 640 has 384. However, the actual shader performance of the UHD Graphics 630 is 212 and the actual shader performance of the GeForce GT 640 is 346. The GeForce GT 640 having 134 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce GT 640 delivers a noticeably smoother and more efficient experience when processing graphical data than the UHD Graphics 630.

The UHD Graphics 630 transistor size technology is 14 nm (nanometers) smaller than the GeForce GT 640. This means that the UHD Graphics 630 is expected to run slightly cooler and achieve higher clock frequencies than the GeForce GT 640. While they exhibit similar graphical performance, the UHD Graphics 630 should consume less power than the GeForce GT 640.

The UHD Graphics 630 requires 15 Watts to run and the GeForce GT 640 requires 65 Watts. We would recommend a PSU with at least 350 Watts for the GeForce GT 640, but we do not have a recommended PSU wattage for the UHD Graphics 630. The GeForce GT 640 requires 50 Watts more than the UHD Graphics 630 to run. The difference is significant enough that the GeForce GT 640 may have a slight adverse affect on your yearly electricity bills in comparison to the UHD Graphics 630.

GPU Mini Review

Mini ReviewOverview Intel UHD Graphics 630 are Integrated Graphics in some of Intel's Coffee Lake Processors. Architecture The Coffee Lake Architecture succeeds the Kaby Lake Architecture and aims for increased CPU and Graphics Performance, within the same Power Requirements. It includes support for DirectX 12.1, OpenCL 2.1 and OpenGL 4.6, as well as DDR4 Memory Support. GPU The central unit initially runs at 300MHz and goes up to 1150MHz in Turbo Mode. The GPU Codenamed GT2 offers 184 Shader Processing Units, 23 TMUs and 3 ROPs Memory Speed The operating memory clock depends on which speed the System's RAM is running and which memory type is installed and is ultimately limited by the highest operating speed that the processor supports. Depending on whether or not the System's RAM is Dual-Channeled, it can access either a 64-bit or 128-bit Memory Interface. Memory Frame Buffer The GPU Shares the System's RAM which varies according to the System. The GPU may reserve up to 1.7GB.Overview
GeForce GT 640 is a Middle-Class Graphics Card based on the first revision of the Kepler Architecture.

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.

GPU
It equips a GPU Codenamed GK107-300-A2 which has 2 Stream Multiprocessor activated and thus offers 384 Shader Processing Units, 32 TMUs and 16 ROPs. The Central Unit is clocked at 902MHz.

Memory
The GPU accesses a 2GB 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 891MHz.

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

Power Consumption
With a rated board TDP of 65W, it requires at least a 350W PSU and it relies entirely on the PCI Slot for power, meaning no extra connectors are required.

Performance
Gaming benchmarks put its performance on average with Radeon HD 6670.

System Suggestions
We recommend a Modest Processor (Intel Core i3) and 8GB of RAM for a system with GeForce GT 640.
