In terms of overall gaming performance, the graphical capabilities of the Intel G4 1050MHz are significantly better than the Nvidia GeForce 840M 2GB.

The GeForce 840M 2GB has a 729 MHz higher core clock speed but 24 fewer Texture Mapping Units than the G4 1050MHz. The lower TMU count doesn't matter, though, as altogether the GeForce 840M 2GB manages to provide 10.3 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 840M 2GB has a 729 MHz higher core clock speed and 5 more Render Output Units than the G4 1050MHz. This results in the GeForce 840M 2GB providing 7.3 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 G4 1050MHz was released over three years more recently than the GeForce 840M 2GB, and so the G4 1050MHz is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the GeForce 840M 2GB when running the latest games.

The GeForce 840M 2GB has 2048 MB video memory, but the G4 1050MHz does not have an entry, so the two GPUs cannot be reliably compared in this area.

Both the G4 1050MHz and the GeForce 840M 2GB have 384 Shader Processing Units. While the two GPUs have the same number of SPUs, the actual performance delivered by the GeForce 840M 2GB is 583 and by the G4 1050MHz is 583. Knowing that the shader performance of the GeForce 840M 2GB is superior, it is not necessary to examine the GPUs' respective Texture and Pixel Fill Rates.

The G4 1050MHz transistor size technology is 18 nm (nanometers) smaller than the GeForce 840M 2GB. This means that the G4 1050MHz is expected to run slightly cooler and achieve higher clock frequencies than the GeForce 840M 2GB.

The G4 1050MHz requires 28 Watts to run and the GeForce 840M 2GB requires 33 Watts. The GeForce 840M 2GB requires 5 Watts more than the G4 1050MHz to run. The difference is not significant enough for the GeForce 840M 2GB to have a noticeably larger impact on your yearly electricity bills than the G4 1050MHz.

GPU Mini Review

Mini ReviewOverview
Intel Iris Plus Graphics G4 1050MHz are integrated graphics in some of Intel's Ice Lake mobile processors. It can be found in Intel Core i5-1030G4 & Intel Core i5-1035G4

The Ice Lake architecture succeeds the Kaby lake architecture and aims for increased CPU and graphics performance.
New Features
These Gen11 graphics solutions include the new Variable Rate Shading (VRS) support. This lets shading time for object shading in game to be allocated more accurately by the game's developers. So for example, a graphics depicting an object that cannot easily be seen can be marked as not needing such high performance and visual accuracy and thus save processing power. GPU
The central unit initially runs at 300MHz and goes up to 1050MHz, in turbo mode.

Because Performance depends heavily on the Memory Bandwidth, it may vary from System to System.
Best case scenario, expect Intel Iris Plus Graphics G4 1050MHz performance to be similar to the AMD Radeon RX Vega 8 GPU.
GeForce 840M 2GB is a Middle-Class Mobile Graphics Card based on the First Revision of the Maxwell architecture.

The Maxwell architecture features many improvements and among them is the extremely large L2 Cache which allows NVIDIA to produce Graphics Cards with relatively small memory data transfer rates, without causing too much impact on the overall performance. Furthermore, the Shaders have been redesigned and are both more powerful and energy efficient.

It equips a GPU codenamed GM108 which has 3 SM activated and thus offers 384 Shader Processing Units, 24 TMUs and 8 ROPs. The central unit runs at 1029MHz and goes up to 1124MHz, in Turbo Mode.

The GPU accesses a 2GB frame buffer of DDR3, through a 64-bit memory interface. The Frame Buffer is exaggerated and in no way benefits the GPU. The memory clock operates at 1001MHz.

DirectX 11.2 Support (11.0 Hardware Default) and support for GPU Boost 2.0, GeForce Experience, PhysX and other technologies.

Power Consumption
With a rated board TDP of 33W, it will only be equipped in average sized notebooks.

Benchmarks indicate its performance is over 20% faster than the older GeForce GT 740M. Therefore, it should match GeForce GT 750M.

System Suggestions
We recommend a modest processor (Intel Core i5 Mobile) and 4GB of RAM for a notebook with GeForce 840M 2GB.
