Long, but yeah... Intel has been doing some cool stuff with the P4. Imagine if you could take some engineers from both companies and make a completely new product.

A few corrections:

1. The L1 data cache is used for only integer/memory address data. All FP data is fetched from the L2 cache. One of the reasons the P4 relies so much on its L2 cache.

2. The L1 cache is also pipelined. Meaning data can be accessed every cycle but it takes 2 cycles for a complete 32-bit integer to be loaded. This wasn't explicitly stated.

3. MMX had some instructions to operate on 64-bit quad operands. They were some logical and/or instructions, no arithmetic.

Spud, do you know what changes are being made to improve Hyper Threading or are the improvements going to come solely from the changes you already mentioned?

Yeah, call it a "Pentathlon". That way it would run good in 5 different benchmarks! LOL!!!!

although it's REALLY long and I havn't gotten all the way through.. I can say I was relieved by this fact and the post wasn't "prescotts going to kick some ass and be really cool because the opteron sucks and is made by amd"
articles like this are why I read these forums.. so I can actually learn things, if I wanted a pissing contest I'd walk down the street to a bar.. speaking of which I have to go now

Big thing as far as I can tell from the available info from Intel and Jack Lo, Henry Emer and Dean Tullsen they are the formost IMO in the theory of Hyper Threading technologies.

With the issue port inscrease and the completely seperate L1 caches as well as the two rapid execution units to feed those caches there shoud be substancial improvements. Occording to what the whitepapers studies and thesis papers say that substantial increases in hyper threading operations are expected from these improvements.

As far as I am concerned this is extremely exciteing technology. With talk that Nocona will be able to do 4 threads instead of two makes it even more exciteing. The Prescott will soar thats for damned sure. By how much over the Northwood is still yet to be seen but I easily see 20%+ accross the board. But thats only my opinion based on my own observations on how the P7 reacts to cache size increases, issue ports, FSB speeds, and register adjustments.

Imgod Im sorry I missed that I dont program yet so that Optimization Manuals are pretty useless to me but I think ill sit down sometime this week and read all that. I could do a code execution comaparision of the P7 K8 cores for everyones reference. But first thing is pulling my Itainium and Intel Compiler posts up.

Thanks, lotta that was over my head, but that was a lot better then "Intel rocks, AMD sucks" or vice versa. As someone new here stuff like this helps to understand what really is going on.

Thanks again!
