In advance of the launch tomorrow, any tech site worth its salt has released a hands-on review of Nvidia’s next line of GPUs. So far the nomenclature of the new series completely resets Nvidia’s old system. Previously, the last Nvidia line of GPUs ended (presumably) at the 9800GX2. Now they are back in the hundreds and have placed a GTX prefix in front of the entire line (so far).
Ok, on to the random bits of information. This beast has 1.4 BILLION transistors. Nvidia’s last high-end card had only 754 million transistors, so we are seeing almost double the brute force capability. Let’s show you a little comparison between a Geforce GTX280 and a top of the line dual core Penryn CPU from Intel:
Now technically, in a simplified sense, the older generation of Nvidia GPUs had 128 cores. Consumer CPUs, at most, have 4 cores. The new generation of Nvidia GPUs has 240 cores. That is an INSANE number of cores compared to a Central Processing Unit. Maybe that’s why the GTX 280 can suck 236 Watts at full bore. Now you might wonder, why not replace or augment your CPU with all of that crazy power in your GPU? Well, the industry is actually moving in that direction. The primary roadblock is the fact that GPUs process data in a very specific, specialized way and CPUs are built to process data in a very general way. GPUs are generally built to work with pixels, while CPUs are built to work with ANY data. We’ve already seen GPUs used by scientists to do brute force calculations much faster than CPUs, and we’ll see a more mainstream/consumer fusion of the two components in late 2009.
So how much faster is it?! Compared to the previous single-card solution from Nvidia, the 9800GTX, it is roughly 50% faster in most games. Running the game Oblivion, here is a benchmark graph stolen from AnandTech.com comparing the top performing GPUs at maximum resolution and maximum detail. This resolution is so high that it is confined to 30 inch monitors, most users will not be pushing their GPU nearly this hard. Score is presented as number of rendered ‘frames’ per second.
The GTX280 will cost $650 and the GTX260 will cost $400.
Nvidia has done it again, the fastest single GPU in existence. AMD/ATI have their work cut out for them, we already know their 4870 wont be as fast as the GTX280, but theoretically the pricing should be MUCH lower and multi-GPU solutions could end up giving them a competitive advantage performance-wise. We’re in the midst of another GPU war! It’ll be a few more days till we get to see direct comparisons between the best from AMD and the best from Nvidia.
I. Can’t. Wait.
