In terms of overall gaming performance, the graphical capabilities of the Intel HD Pentium G840 are significantly better than the Nvidia Quadro4 780 XGL.

The HD Pentium G840 was released over three years more recently than the Quadro4 780 XGL, and so the HD Pentium G840 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the Quadro4 780 XGL 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 Quadro4 780 XGL has 128 MB video memory, but the HD Pentium G840 does not have an entry, so the two GPUs cannot be reliably compared in this area.

The Quadro4 780 XGL has 4 Shader Processing Units and the HD Pentium G840 has 6. However, the actual shader performance of the Quadro4 780 XGL is 1 and the actual shader performance of the HD Pentium G840 is 16. The HD Pentium G840 having 15 better shader performance and an altogether better performance when taking into account other relevant data means that the HD Pentium G840 delivers a marginally smoother and more efficient experience when processing graphical data than the Quadro4 780 XGL.

GPU Mini Review

Mini ReviewQuadro4 780 XGL is a professional graphics card that will deliver similar gaming performance to GeForce4 Ti 4400, though worse due to the lack of support for gaming drivers.Intel 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.
