In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R7 250X are massively better than the Intel HD Pentium G4400.

The Radeon R7 250X has a 600 MHz higher core clock speed and 32 more Texture Mapping Units than the HD Pentium G4400. This results in the Radeon R7 250X providing 35.2 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 Radeon R7 250X has a 600 MHz higher core clock speed and 12 more Render Output Units than the HD Pentium G4400. This results in the Radeon R7 250X providing 13.8 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 HD Pentium G4400 was released over a year more recently than the Radeon R7 250X, and so the HD Pentium G4400 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the Radeon R7 250X.

The Radeon R7 250X has 2048 MB video memory, but the HD Pentium G4400 does not have an entry, so the two GPUs cannot be reliably compared in this area.

The HD Pentium G4400 has 12 Shader Processing Units and the Radeon R7 250X has 640. However, the actual shader performance of the HD Pentium G4400 is 96 and the actual shader performance of the Radeon R7 250X is 517. The Radeon R7 250X having 421 better shader performance and an altogether better performance when taking into account other relevant data means that the Radeon R7 250X delivers a massively smoother and more efficient experience when processing graphical data than the HD Pentium G4400.

The HD Pentium G4400 transistor size technology is 14 nm (nanometers) smaller than the Radeon R7 250X. This means that the HD Pentium G4400 is expected to run slightly cooler and achieve higher clock frequencies than the Radeon R7 250X.

The HD Pentium G4400 requires 47 Watts to run and the Radeon R7 250X requires 80 Watts. We would recommend a PSU with at least 300 Watts for the HD Pentium G4400 and a PSU with at least 450 Watts for the Radeon R7 250X. The Radeon R7 250X requires 33 Watts more than the HD Pentium G4400 to run. The difference is significant enough that the Radeon R7 250X may have a slight adverse affect on your yearly electricity bills in comparison to the HD Pentium G4400.

GPU Mini Review

Mini ReviewOverview
Intel HD Pentium G4400 is the specific version of Intel HD Graphics 510 Desktop that is integrated in the Pentium G4400 Processor.

The Skylake Core includes support for DirectX 12.1, OpenCL 2.0 and OpenGL 4.4. Additionally, it also supports DDR4 Memory.

It equips a GPU Codenamed GT1 which offers 12 Shader Processing Units, 8 TMUs and 4 ROPs. The Central Unit Initially Runs at 350MHz and goes up to 1000MHz, in Turbo Mode.

The GPU Shares the System's RAM which varies from laptop to laptop. Typically, the GPU reserves 1.7GB. Depending on whether or not the system's RAM is Dual-Channeled, it can access either a 64-bit or 128-bit memory interface. The operating memory clock also depends on the at which speed the System's RAM is running and is limited by the highest operating speed that the Processor supports. In this case, it is 1067MHz.
It is then obvious the Memory Bandwidth depends on a lot of factors and thus this Graphics Card performance may vary heavily from system to system.

Gaming benchmarks put its performance almost on level with the older Intel HD Graphics 4400.

System Suggestions
Intel HD Pentium G4400 is best suited for resolutions up to and including 1366x768. We recommend a Decent Processor and 4GB of RAM for Optimal Performance.
Radeon R7 250X is a fast-middle-class Graphics Card based on the Graphics Core Next architecture. It offers the Cape Verde XT GPU.
The Cape Verde XT Core is a GCN 1.1 GPU and was first seen on Radeon HD 7770 and then re-used in the OEM only Radeon HD 8760.
It offers 640 Shader Processing Units, 40 TMUs and 16 ROPs, on a 128-bits memory interface of fast GDDR5.
Radeon R7 250X comes clocked at 950MHz (though there might be some 1GHz versions) and has its operating memory clock set at 1125MHz. The rated TDP board is of 80W and the release price around $99.
This card should come in 1GB and 2GB versions, though both will offer the same performance.
Its performance has proven to be exactly like Radeon HD 7770 GHz Edition (if clocked at 1GHz) and thus this card is not suited for 1080p gaming but it can handle 720p with ease. The 950MHz versions will be around 3% slower.
