Paul,

I think it is reasonable to expect K7 FPU performance to be very similar to the 21264 numbers below. The K7 actually appears to have more FPU hardware than the 21264.

In actual testing, the 575 MHz 21264 receives a SPECint95 rating of 30.1 and a SPECfp95 rating of 44.8. For comparison, a 296 MHz UltraSPARC II obtains a SPECint95 score of 13.2 and a SPECfp95 score of 18.4. The Intel Xeon is further below on the scale, with the 400 MHz version receiving a SPECint95 score of 16.3 and a value of 13.2 for floating point performance. It is obvious from these benchmarks that both Sun and Digital value floating point performance much more than Intel.

Compaq breaks for border with Alpha chip

Another flurry of snow flakes from our mole at Compaq who must be very deep within the company, judging from the information.

Towards the end of the month, we are due to meet one Bill Herrick, a senior Compaq executive on the Alpha platform. He is the author of this SlideWare so we are now fully armed and ready for the meeting.

The insider slipped us the PowerPoint presentation which is far too big to upload (for us) or download (for you).

Instead, we have printed the slide outline as a PDF file, which you can download from here.

What's significant is the emphasis Compaq is putting on comparisons between its Alpha and the rest. We can't see a mention of Merced in here anywhere.

The symmetric multiprocessing in EV8 codenamed Arana isn't in this set of slides but compares extremely favourably to IA-64 Merced.

But EV8 and onwards might require the help of Kryotech and its cool technology, we are given to understand. We're looking forward to the 1000MHz EV68 this year.

And the slides mention that Compaq is a fabless company, so expect much of this stuff from Samsung...

As we are not being invited to Compaq Innovate this year for some reason or other, we won't be able to meet our mole in person... ®
