GeForce 8400 GS 512MB vs Radeon HD 4350

Intro

The GeForce 8400 GS 512MB has a core clock speed of 650 MHz and a DDR2 memory speed of 400 MHz. It also makes use of a 64-bit memory bus, and uses a 80 nm design. It features 16 SPUs, 8 TAUs, and 4 ROPs.

Compare those specs to the Radeon HD 4350, which features GPU clock speed of 575 MHz, and 512 MB of DDR2 memory running at 500 MHz through a 64-bit bus. It also is made up of 80(16x5) Stream Processors, 8 Texture Address Units, and 4 ROPs.

GeForce 8400 GS 512MB 40 Watts
Difference: 18 Watts (82%)

Memory Bandwidth

In theory, the Radeon HD 4350 should be 25% faster than the GeForce 8400 GS 512MB overall, due to its greater data rate. (explain)

Radeon HD 4350 8000 MB/sec
GeForce 8400 GS 512MB 6400 MB/sec
Difference: 1600 (25%)

Texel Rate

The GeForce 8400 GS 512MB will be a small bit (about 13%) better at anisotropic filtering than the Radeon HD 4350. (explain)

GeForce 8400 GS 512MB 5200 Mtexels/sec
Radeon HD 4350 4600 Mtexels/sec
Difference: 600 (13%)

Pixel Rate

The GeForce 8400 GS 512MB is just a bit (approximately 13%) better at full screen anti-aliasing than the Radeon HD 4350, and should be able to handle higher screen resolutions better. (explain)

GeForce 8400 GS 512MB 2600 Mpixels/sec
Radeon HD 4350 2300 Mpixels/sec
Difference: 300 (13%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Memory bandwidth is the max amount of data (measured in MB per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory speed. In the case of DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.

Hi, thanks for the excellent comparison. I had ge force 8400 gs (512 MB, GDDR2) installed on my pc. In windows experience rating this card was rated 3.9 (lowest score in that rating as well). Then, I replaced ge force with the ati radeon hd 4350 (1 GB hyper memory, 512 MB DDR3) and, on my surprise, the windows experience rating came down to 3.3. However, it seems that some games that were unplayable with the ge force card I can (with lot of patience) play with the ati card.
So, I remain confused but determined to get some "proper" card asap. Regards

Weird... I wouldn't take the Windows Experience thing too seriously then. 😛
Both those cards are pretty slow though... I personally have a GeForce 9800GT and even though it's quite old now, it's waaaaaaay faster than both of those.

You might need a new power supply though. 🙂

hi i have two cards, 8400 gs 512 and ati radeon 4350 and when i test them in the same machine i found that the 4350 is better than 8400 GS
