NVIDIA thanks Intel for saying GPUs are 'only' 14 times faster than CPUs
Well, we've gone a full month since the last episode of NVIDIA's and Intel's ongoing public feud, but it looks like Intel has now stoked the flames once again (albeit inadvertently) in a paper presented at the recent International Symposium on Computer Architecture. That attempted to debunk the "100X GPU vs. CPU myth," but it also contained the tidbit that GPUs are "only" up to 14 times faster than CPUs in running application kernels, which NVIDIA has more than a happily latched onto. In a blog post, NVIDIA's Andy Keane says that it's a "rare day" when a competitor states that their technology is only 14x faster, and that he can't recall another time when he's "seen a company promote competitive benchmarks that are an order of magnitude slower." Of course, he then further goes on to note that Intel's tests were done with NVIDIA's previous generation GeForce GTX 280, and that the codes were simply run out-of-the-box without any optimization -- but, still, he seems more than happy to accept this bit of "recognition." In Intel's defense, however, the overall finding of the paper (linked below) is that the performance gap between a GTX 280 GPU and Core i7 960 processor is actually just 2.5X "on average," which NVIDIA hasn't highlighted for some reason.
Intel Celeron, Core i7, and Atom lineup leaked?
The sun rises, seasons change, CPUs get faster, and Intel's plans get leaked. That's the way it works, so while this report from Digitimes listing out Intel's chip releases through the beginning of next year should be taken with a grain of salt, feel free to make it a small one. Apparently there's a new line of celery-packing Celeron processors coming in Q3 called E3000, starting with the 2.4GHz E3200 and the 2.5GHz E3300. Both feature 1MB of L2 cache, 800MHz FSB, 65W power consumption, and hardware virtualization, meaning either can take you to XP-on-Win7 nerdvana. There will also be a new Core i7 960 chip with a core frequency of 3.2GHz in the fourth quarter, which is also when the nettop-intended dual-core Atom D510 will drop, while the more portable-friendly dual-core Atom D410 won't release until Q1 next year -- bad news for those who'd been hoping for a speedier netbook under the Christmas tree.
