In terms of overall gaming performance, the graphical capabilities of the Intel HD Pentium G840 are significantly better than the Intel G43 Express Chipset.

The HD Pentium G840 was released over a year more recently than the G43 Express Chipset, and so the HD Pentium G840 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the G43 Express Chipset.

Both GPUs exhibit very poor performance, so rather than upgrading from one to the other you should consider looking at more powerful GPUs. Neither of these will be able to run the latest games in any playable way.

The HD Pentium G840 and the G43 Express Chipset have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The HD Pentium G840 has 10.7 GB/sec greater memory bandwidth than the G43 Express Chipset, which means that the memory performance of the HD Pentium G840 is slightly better than the G43 Express Chipset.

The HD Pentium G840 has 6 Shader Processing Units but the G43 Express Chipset does not have an entry, so the two GPUs cannot be reliably compared in this area.

The G43 Express Chipset requires 24 Watts to run but there is no entry for the HD Pentium G840.

GPU Mini Review

Mini ReviewIntel HD Pentium G840 is a specific version of the Intel HD Graphics that comes embedded on the CPU 'Pentium G840 2.8GHz'.
It's based on the Sandy Bridge architecture, meaning it features 6 SPUs. The GPU's clock is initially set at 850MHz and can go to up to 1150MHz. The max memory type supported is DDR3 1333MHz - therefore, the GPU's max memory clock is 667MHz.
Intel HD Pentium G840's gaming performance is very limited and so most games will have to be played at very reduced settings while extremely demanding games are probably out of the question.
Intel G43 Express Chipset comes embedded on the Core 2 Quad/Core 2 Duo CPUS and features an Integrated GPU called Intel GMA X4500.
Due to its characteristics (e.g. Shared Memory) the performance is very limited but might be enough to play today's games at low settings excluding, however, very demanding games like Metro 2033 or The Witcher II, that are unplayable, even at the lowest settings.
