In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 6800 XT are noticeably better than the Intel HD Pentium G620.

The HD Pentium G620 was released over three years more recently than the GeForce 6800 XT, and so the HD Pentium G620 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the GeForce 6800 XT when running the latest games.

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 GeForce 6800 XT has 256 MB video memory, but the HD Pentium G620 does not have an entry, so the two GPUs cannot be reliably compared in this area.

The HD Pentium G620 has 6 Shader Processing Units and the GeForce 6800 XT has 12. However, the actual shader performance of the HD Pentium G620 is 16 and the actual shader performance of the GeForce 6800 XT is 4. The HD Pentium G620 having 12 better shader performance and an altogether better performance when taking into account other relevant data means that the HD Pentium G620 delivers a marginally smoother and more efficient experience when processing graphical data than the GeForce 6800 XT.

GPU Mini Review

Mini ReviewIntel HD Pentium G620 is a specific version of the Intel HD Graphics that comes embedded on the CPU 'Pentium G620 2.6GHz'.
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 1100MHz. The max memory type supported is DDR3 1066MHz - therefore, the GPU's max memory clock is 533MHz.
Intel HD Pentium G620'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.
The groundbreaking new NVIDIA GeForce 6800 graphics processing units (GPUs) and their revolutionary technologies power worlds where reality and fantasy meet; worlds in which new standards are set for visual realism and quality, performance, and video functionality. The GeForce 6800 GPUs deliver powerful, elegant graphics to drench your senses, immersing you in unparalleled worlds of visual effects for the ultimate PC experience.
