Intel outlines benchmarks for HT Pentium 4/800 using DDR 400
Speculative branching for Springdale
By Mike Magee: Monday 16 December 2002, 19:26
ALL OF THE BENCHMARKS we saw for the different kinds of Pentium 4 using DDR 400 and DDR 333 over the weekend must be somewhat speculative on Intel's behalf.
This is why the guy who showed us the stuff said scribble down the figures while you can – they might change just as roadmaps do from time to time.
The benchmarks compare the Springdales that use DDR-400 memory with the current rash of Intel chipsets.
We saw several sets of benchmarks and can summarise them below.
Intel has figures for SPECint_base2000 and SPECfp_base2000, normalised against a 3.06GHz Pentium 4 with Hyperthreading and using 845GE chipset and DDR 333 memory. The measurements use discrete graphics and are for systems using 512MB of memory in each case.
SPECint_base2000 (integer)
Pentium 4, 3.06GHz, 533MHz, HT, 845GE, DDR 333 1.00
Pentium 4, 3.06Ghz, 533MHz, HT, Springdale and DDR 333 1.04
Pentium 4, 3GHz, 800MHz, HT, Springdale and DDR 400 1.09
SPECfp_base2000 (floating point)
Pentium 4, 3.06GHz, 533MHz, HT, 845GE, DDR 333 1.00
Pentium 4, 3.06Ghz, 533MHz, HT, Springdale and DDR 333 1.26
Pentium 4, 3GHz, 800MHz, HT, Springdale and DDR 400 1.36

Hypethreading Benchmarks
Intel claims additional features of hyperthreading mean the Springdale, using a 800MHz front side bus and a 3GHz Pentium 4 will deliver 43 per cent multitasking performance over the 845PE chipset using the 533MHz system bus. µ
* THE SAME document showed "positive press coverage" across print, TV, and Web sites. Those quoted as endorsing Hypethreading were [H]ardOCP, Ace's Hardware, Extreme Tech and Cnet. Intel reached over 1,000 press and analysts when it launched the 3.06GHz, apparently. It got two of us from the INQ, that's for sure, so reaching its "critical mass" target. However, no-one at the INQ has been let loose on HT technology yet, unless Andrew Thomas has got one in his bottom drawer and hasn't told us yet. Our jury of four is, therefore, still out on this technology...
