Zotac GeForce GTX 465

Nvidia advantage of Computex, which will open tomorrow in Taipei to announce a new version of the GF100, the GeForce GTX 465. Zotac, that we thank and will be one of the first to offer the card in France, could send us a review sample on the wire. This happened just hours before leaving for Taiwan but we still have time to run all our benchmarks. However, we have to ignore the noise measurements and thermography, points to which we return when we return.

The GeForce GTX 465

The new GeForce GTX 400 uses the same GPU as its big sisters, the GF100. If it remains clocked at the same frequency as in the version of GeForce GTX 470 (607 MHz), he was however cut a few additional units. So, it only has 11 multi asset of 16 (against 15 for the GTX 480 and 14 for the GTX 470) or 352 “cores”, and memory bus reduced to 256 bits, mechanically resulting in the reduction of ROPs to 32.

in terms of internal organization, the GF100 is a reminder consists of 4 big main blocks, each containing 4 GPCs multiprocessors (SMs). With 5 multi-less in the GPU of the GeForce GTX 465, NVIDIA indicates that a complete GPC is disabled and one of the 3 remaining GPCs sees amputated a multiprocessor or 4/4/3/0. Roughly it is therefore a configuration similar to that of the GeForce GTX 480, but with a GPC less. According to reports we have received, there are other configurations (4/3/2 / 2 for example), a detail of course, but may slightly impact performance. Nvidia, however, said that this was not correct and that all GF100 dedicated to the GeForce GTX 465 would have a good 4/4/3/0 type of configuration.

The card Zotac has given us one of the first batches using an identical design to that of the GeForce GTX 470. Including at the PCB which differs simply by the absence of 2 memory modules since only 256-bit memory buses used on cable 320 bits on the PCB. This model of GeForce GTX 470, manufactured by NVIDIA which delivers complete card partners to ensure a coordinated launch, however, only be available in small volume. The different card manufacturers then receive only GPUs (or rather GPU + memory bundles) and will be responsible for the manufacture of PCBs and the choice of the cooling system.
