Core 2 Extreme 40% faster than Pentium EE 965?
Marc writes "As far as I know, this is the first time that Intel has talked about what we can expect from its new gaming CPU, Core 2 Extreme. For once, there is no word on power consumption on this new chip, but Intel talks about raw speed and a 40% gain over the current 3.73 GHz Extreme Edition 965 - which would be rather impressive and could indicate a problem for AMD. In this interview with TG Daily, Intel also claims that a Core 2 Extreme-based enthusiast PC will leave the pixel power of a Playstation 3 in the dust. Gamers, this appears to become the most exciting year for you in a long time!"
Because the ugly x86 instruction set acts as a form of compression, x86 code is more dense and fits more easily into the instruction cache than RISC code. The overhead of translating x86 to internal RISC is basically fixed and is therefore getting smaller each process shrink. It's already negligble. For this reason, the ugly x86 instruction encodings are now an advantage! x86 also gained an additional 8 registers and a cleanup with AMD64.
Hm. I knew it was one of those.
Incidentally, the 386 DX 40 was the one AMD made. Intel was rather peeved at them for licensing the design and then making it run faster than the fastest Intel chip.
Ok so the clock speed rocks. But does the rest of the system keep up? The big advantage I see with AMD is Hyper Transport and the newly ratified Hyper Transport 3.0. You can have a THz CPU but if you can't feed it data/instructions it's just going to waste most of it's potential.
I'm not familiar with any possible new bus technology coming out with the new Intel CPU's, but based on my current experience with the latest Dell boxes (Intel) and our new Penguin Computing and HP AMD boxes Intel has a lot of catchup to do to outperform AMD and their whole architecture.
We are using these boxes as MySQL database servers with each server containing 100+ 500 MB to 50 GB databases attached to fiber channel disk arrays. These boxes are mostly doing I/O, but a fair amount of CPU is used for sorting/math done at the database level. The AMD boxes smoke the Intel ones.
Unless Intel also releases a whole new architecture that can compete with Hyper Transport the extra speed will most likely be wasted.
I'm so glad that AMD became a powerful player in the desktop PC and server market... not because I love AMD but because now we are really seeing some earnest competition and innovation. Before, we were happy with Moore's law, but then AMD beat Intel to 1GHz and the ensuing struggle for mind and market share has brought about some truly phenominal changes.
Keep up the excellent competition... maybe we can have a third player jump in with some new ideas? IBM? Sun? Let's see you what you have...
