I don't know anything about AMD CPUs as I've never built one, but I do find it interesting they blanked out the core voltage field in CPU-Z. Why can't some of these folks give us some FPS benchmarks for fun?

Jeeze, and I thought I was doing good with a little E8400 that has hit 4.4GHz on air stable under Prime95. (Run it at 4.2 full time).

Sir, that's some funky math :) . GHz do not represent processing power unless you restrict the comparison to a particular architecture. You can instead do 4 * core_flops for an idea of how powerful the CPU is. This allows you to compare the number with other CPUs even with different architectures. Just my 2$/100.

heh a Pentium 4 years ago hit 7.3 but sadly enough a stock E6600 (2.4ghz) blows it in superpi, now 4 cores capable - amazing.

Is that all 4 cores, cache etc? and how solid and for how long?

Well, what was the superpi score? I read about 5 months ago about someone breaking 7GHz with an E8600, and they were happy to report their superpi 1M score of just under 7 sec. I don't know what the maximum overclock has been with an intel core2 quadcore, but I don't think they will go as high as the dual cores.

Seriously though, extreme overclocking is pretty pointless as they only showcase the architecture and nothing else. Performance/clock and performance/power are thrown out the window at those speeds. I’d love to have a 10GHz 16 core i7 to run GTA IV though.

dreamphantom_1977http://www.ripping.org/database.php?cpuid=360world record- intel = 8220.1world record- amd = 6696.


Actually, the record of 8.2GHz refers to a single core Celeron class CPU.

If you restrict yourself to a quad vs quad comparison it is
AMD - 7.1GHz
Intel - 6.2GHz (Yorkfield; Kentsfield was ~5.2GHz)

Pics and video or it didn't happen.

This is more than likely a fake. I read about this on another site over a day ago and there is much speculation that LimitTeam modified the numbers by exploiting a flaw in CPU-Z.

~3 days ago, a Chinese overclocking team also claimed they reached 7.2GHz, but that was shown to be fake.

I think power (heat) increases linearly with frequency and exponentially with voltage. Pentium extreme 965 was 3.73 GHz stock and 570 and 670 were 3.8 GHz. They were the highest stock speeds as far as I know. The 570 and 670 were only single core but the extreme 965 was dual core.

Nope. The AMD guys probably used liquid helium, but there's no info much for the 7.1GHz OC.

Wouldn't be much different from the stock speeds. Most games are GPU dependant, hence why the Core i7 stock doesn't grab much extra performance over a dual core or triple core AMD. The games benchmarks would just bottlneck in the GPU.

The 7.1 GHz Phenom II will still kick the 8.1 GHz Pentium 4's butt. Just because of P4's deeper pipelines. It's inefficient.

Just the thought that the ALU is running at 16.2 GHz on that chip is just like WTF?!?! Since Pentium 4's ALU always runs twice the speed of the CPU which is just insane!

all these clocks and cores are great, but im really exited about the new steps being taken in multi-core processing, ive heard some babble talk about sub-cores within cores being the next gen philosophy so when we finally get 1000 or so relative core processors we might have true AI on our hands with cpu's writing and designing efficient software and even more efficient hardware? just wondering how far away are we, any thoughts?

Correct but voltage has to be increased as frequency increases to satisfy the switching requirements of the transistor gates, so technically you're right, but also wrong at high frequency.

It isn't entirely impossible though. We already have a mainstream CPU clocked at 3.33 ghz, and stated by another poster that the Pentium D 960/965 was at 3.6/3.73 (cannot remember exact numbers). Perhaps the 32nm or 28nm fab will be the final push to give us mainstream 3.5ghz+ chips (with respect to heat dissipation that is).

Not really impressed by these world record overclockers unless there's a major distinction between totally enclosed case overclocking and open case overclocking. I'd be impressed if the record was done in a normal mid-tower case where all cooling components are within the case. Otherwise all we have is a motherboard plopped on a table where anything can happen. A room size cooling system to support a motherboard the size of a checker board is nothing short of an old UNIVAC. For now pretty cheap and gimmicky PR for both AMD and Intel.

I could overclock it faster, but I don't feel like using a $15K helium cryostat and a vacuum chamber for that purpose. At 4.1K, it might even superconduct.

i7's run waaaaaay to hot when overclocked for me to buy one, im betting on the 25 degree celcius lower OC temps on the phenom 2's will go along way in terms of LONGEVITY and RELIABILITY of processor and the overclock aswell,

once you go past stock voltage, sense and reason is thrown out the window.
people can talk all the trash they want about it being designed for it or some blather of the sort, more heat breaks things down faster, alot faster, period.
its like some of these wannabe motorheads saying they are gonna overboost thier turbo car from 10psi to 40psi on a stock motor and saying oh yeah i got 200,000 miles out of it, Never ever gonna happen. even with the best tune. as heat goes up thermal wear and breakdown occurs exponentially. im quite sure this is definitly true with processors.

when it comes to games the i7's OC vs phenom 2's OC are virtually the same when it comes to fps, they perform almost identically. honestly the i7's are benchmark queens, unless your encoding video all day you wont see the memory architechture gains displayed.

id say less than 1% of people who run PC's are video editors on the level that will ever see those 2 second compiling advantages or whatever,

yes Im a film student.
