In terms of overall gaming performance, the graphical capabilities of the Intel HD Pentium G1620 are significantly better than the Nvidia Quadro4 780 XGL.

The HD Pentium G1620 has a 375 MHz higher core clock speed than the Quadro4 780 XGL, but the Quadro4 780 XGL has 6 more Texture Mapping Units than the HD Pentium G1620. As a result, the Quadro4 780 XGL exhibits a 0.9 GTexel/s better Texture Fill Rate than the HD Pentium G1620. Neither of these GPUs support DirectX 10 or higher, so Texture Rate holds more weight than when comparing more modern GPUs.

The HD Pentium G1620 has a 375 MHz higher core clock speed but 2 fewer Render Output Units than the Quadro4 780 XGL. The lower ROP count doesn't matter, though, as altogether the HD Pentium G1620 manages to provide 0.2 GPixel/s better pixeling performance. The HD Pentium G1620 supports up to DirectX 11.1, so pixeling performance is not particularly relevant for this GPU. It would be relevant for comparing the Quadro4 780 XGL with other old GPUs, but in this case it is probably safe to say that the HD Pentium G1620 is superior.

The HD Pentium G1620 was released over three years more recently than the Quadro4 780 XGL, and so the HD Pentium G1620 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 G1620 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 G1620 has 16. However, the actual shader performance of the Quadro4 780 XGL is 1 and the actual shader performance of the HD Pentium G1620 is 51. The HD Pentium G1620 having 50 better shader performance and an altogether better performance when taking into account other relevant data means that the HD Pentium G1620 delivers a marginally smoother and more efficient experience when processing graphical data than the Quadro4 780 XGL.

The HD Pentium G1620 transistor size technology is 128 nm (nanometers) smaller than the Quadro4 780 XGL. This means that the HD Pentium G1620 is expected to run massively cooler and achieve higher clock frequencies than the Quadro4 780 XGL. While they exhibit similar graphical performance, the HD Pentium G1620 should consume less power than the Quadro4 780 XGL.

The HD Pentium G1620 requires 55 Watts to run but there is no entry for 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 G1620 is a specific version of the Intel HD Graphics that comes embedded on the CPU 'Pentium G1620 2.7GHz'.
It's based on the Ivy Bridge architecture, meaning it features 6 SPUs. The GPU's clock is initially set at 550MHz and can go to up to 1050MHz. The max memory type supported is DDR3 1333MHz - therefore, the GFU's max memory clock is 667MHz.
Intel HD Pentium G1620'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.
