New Pentium 5 Details - 5-7ghz?
zymano writes "This article gives some details on Pentium 5. It will have 64 bit extensions and maybe a 4000 mhz frontside bus. Quote from the article,'The Pentium V is likely to fly along at between 5GHz to 7GHz, have 2MB plus of level two cache, be built on a 90 nanometer process, and have a stackable design. '"
The chip will sample internally at Intel in January 2004 and will take between four to six months to get to market. The Pentium 6 will follow a very similar schedule.
The Pentium V is likely to fly along at between 5GHz to 7GHz, have 2MB plus of level two cache, be built on a 90 nanometer process, and have a stackable design.
The processor we believe, sits in the LGA 775 pin socket, and above it is a very thin heatsink. But, according to sources close to the firm's plans, another permeable heatsink can sit between this and another microprocessor module, giving a stackable design.
The final design of this arrangement is not set in stone.
According to this source, and the details have not been confirmed, a module sitting on top could provide 64-bit extensions.
And the source claimed, Microsoft is ready to launch a version of Windows called Elements with 64-bit extensions.
The idea seems to be that people can buy a 32-bit module, and then add in the 64-bit processor.
There are three samples of an arrangement of the Pentium V here in Taiwan this week, with a very thin processor and lots of wires and patches stuck on it, just to show proof of concept.
The Pentium V could have a front side bus speed of as much as 4000MHz, the source claimed, although this may be reserved for the next chip along, the Nehalem.
Looks good for your age..
P-V should have 64bit extensions for both pointers and basic math.
64bit pointers and basic math on those pointers, are really what people desire so that more than 4GB can be trivially addressed in a single process's virtual memory space. Think about people who want to manipulate a video file that is larger than 4GB.
AltiVEC **128 bit** is just wide data manipulation and is of no use for those that require large memory footprints. It has the same 32 bit address lines and pointers at a 60MHz Pentium I.
That being said, P-V should also have more than the current 36 bit of physical address lines. I'm guessing they will have 40 usable bits or so of the address bus to physically address memory.
So if you want to put in more than 4GB of RAM you can. But if you don't, 64 bits will be useful to address more than 4GB of a video file sitting in virtual memory.
Yes, thats exactly what they are doing. The P4 pipeline is 20 stages, and the P3s is something like 10. The longer pipeline helps them to ramp up speed, but at the cost of efficiency. Wheeeee.
There will be a heatsink inbetween the stacked processors, although it would be more properly named a heat spreader. They just call it permeable because it will have holes drilled into it so pins can attach to the lower processor.

I can't speak for SCSI, Firewire, SIDE, or any other drive techs 'cause I'm a cheap S.O.B. and won't pay the big bucks for them.
We moved an application from 2 UltraSPARC III 750 MHz CPU's to 6 UltraSPARC III Cu 900 MHz CPU's and saw very little improvement in performance. Then we moved the disk for the application from 9 internal drives to 20 external SCSI over FC drives, and voila our IO wait dropped from 60% or so to 10% +/-. Our query response times dropped by a factor of three or more. Faster, and even more, CPU's are not the answer to data intensive problems, I/O is. Slower (clock speed wise) 64bit CPU's, with better efficiency, more memory addressing, etc. are the norm in the data center for just this reason. IF you can take advantage of your L1/L2 cache then faster clock speed on the CPU will improve performance. The reason most Intel PC's benchmark better than an older box is because the disk, memory and video sub-systems have improved, not because the CPU is making a huge difference.
As proof, search SPEC's benchmark results using Dell and then Sun as your search criteria. Notice the following:
Theoretically the PE2650 should outperform the PE2550 and 280R by about 3 times, all other factors being equal (i.e. same benchmark). The SPEC benchmark does its absolute best to eliminate I/O systems and network interfaces as a factor, so if we are just talking CPU, cache and memory, the Xeon should have had a CINT baseline of about 1600 or so.
Things get even worse when you start looking at the SMP capabilities and scalability. In a truly linearly scalable SMP system you should be able to go from 1 CPU to 2 CPU's and have the benchmark double. Even the best SMP systems (Sun UltraSPARC and IBM Power) can't quite achieve that. But Itanium really has trouble. Search on Dell and look at the CINT and CFP rates benchmarks. Look at 1, 2 and 4 CPU scores for the Dell 7150.
Bottom line? If you are doing heavy lifting on a server, go SMP with 64bit RISC, or, in some cases, use a cluster of 2 CPU x86 servers. If you are a PC user, you are unlikely to see a significant performance increase with new Intel CPU's unless you upgrade the whole system, not just the CPU.
This whole thing of adding clock cycles and deepening the pipeline is not working out well.
