Prescott details
« on: January 07, 2004, 07:30:11 AM »
Happy New Year to you guys and gals. And what better way to start the new year off than with some information about the upcoming version of Intel's Pentium 4 with the Prescott core?
Ace's Hardware has some interesting details about the Prescot core.

bigger D-L1 cache (16 KB instead of 8 KB) & L2-cache (1 MB instead of 512 KB) .. No comments necessary
4x Improved Clock Distribution (compared to Northwood) for better Frequency Scaling
Automated design of the functional blocks for better clockscaling
Improved Imul latency : Northwood/Willamette do their integer multiplications on the FPU, and the big latency is due routing the data between integer and FP datapaths. Prescott has a dedicated integer multiplier. (Thanks goes to Heikki Kultala).
Prescott New Instructions (SSE-3), which will not improve performance at the launch (needs optimized software).
Additional WC Buffers. Instead of sending small pieces of data to the AGP videocard, these pieces of data are stored together in buffers, and send through in one big burst. This helps to preserve FSB bandwidth as the bandwidth of the FSB is more efficiently used (less overhead from one big burst than from many small ones)
Improved Pre-Fetcher Branch Predictor. I did not get much info on this but it seems that the buffers have been made bigger so the branch predictor will be able to cope better with more then one thread.
Improved Hyperthreading: two new instructions: Monitor and Wait, which will only improve performance on recompiled software.
Have a look at Ace's Hardware for what else is new, and what performance can be expected.

Hi guys! the last week i have bought my new pc:
M.B. Asus Pc4c800 e deluxe, ram 512 mb ddr 400, PRESCOTT 3 GzHZ, hdd 120 gb S-Ata, Radeon 9800 pro.
The only thing I can tell you is that running 3d mark 03 I have beaten my brother that has the same pc but with the 3ghz (not prescott) and the radeon 9800 xt!
AMAZING!!!!!!!!!!!  http://images.thetechguide.com/forum/public/style_emoticons/<#EMO_DIR#>/tongue.gif\' class=\'bbc_emoticon\' alt=\':P\' />

My case show thermal heat and I can say that it is okay even if the reviews I read did show different results; I have pushed my Prescott from 3ghz to 3,5ghz and it was okay!
Great games experience!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!  http://images.thetechguide.com/forum/public/style_emoticons/<#EMO_DIR#>/cool.gif\' class=\'bbc_emoticon\' alt=\'B)\' />
