In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 7300 LE are marginally better than the Intel GMA 3100.
The GMA 3100 was released over a year more recently than the GeForce 7300 LE, and so the GMA 3100 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GeForce 7300 LE.
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 GMA 3100 and the GeForce 7300 LE have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.
The GeForce 7300 LE has 5.3 GB/sec greater memory bandwidth than the GMA 3100, which means that the memory performance of the GeForce 7300 LE is marginally better than the GMA 3100.
The GMA 3100 has 128 Shader Processing Units and the GeForce 7300 LE has 8. However, the actual shader performance of the GMA 3100 is 51 and the actual shader performance of the GeForce 7300 LE is 4. The GMA 3100 having 47 better shader performance is not particularly notable, as altogether the GeForce 7300 LE performs better when taking into account other relevant data.
The GMA 3100 requires 17 Watts to run and the GeForce 7300 LE requires 23 Watts. We would recommend a PSU with at least 350 Watts for the GeForce 7300 LE, but we do not have a recommended PSU wattage for the GMA 3100. The GeForce 7300 LE requires 6 Watts more than the GMA 3100 to run. The difference is not significant enough for the GeForce 7300 LE to have a noticeably larger impact on your yearly electricity bills than the GMA 3100.
The Intel Graphics Media Accelerator, or GMA, is Intel's current line of integrated graphics processors built into various motherboard chipsets.
These integrated graphics products allow a computer to be built without a separate graphics card, which can reduce cost, power consumption and noise. They are commonly found on low-priced notebook and desktop computers as well as business computers, which do not need high levels of graphics capability. 90% of all PCs sold have integrated graphics. They rely on the computer's main memory for storage, which imposes a performance penalty, as both the CPU and GPU have to access memory over the same bus.
The NVIDIA GeForce 7 Series graphics processing units (GPUs) represent a significant leap forward in 3D graphics design, delivering the unparalleled horsepower and revolutionary technologies you need to tackle the latest games and video applications. The GeForce 7 Series GPUs deliver blazing frame rates and outstanding image quality so you can experience full-throttle graphics performance.
