HT3.0 vs HT1.0

[Dustbag]

Hi,

I have read several different reports on the affect of HT3.0 vs HT1.0 and I would like to know does anyone have a definitive answer?

I use the PC exclusively for gaming and would like to know how much HT3.0 vs HT1.0 going to affect the speed?

Thanks,
Dusty

Normally the bus speed has little to no effect in system performance, as a reference measure, gothitbycar, a member of this forum, decided to make a small comparison with his system, you can take a look at it here: http://www.tomshardware.com/forum/59362-28-hypertransport-speed-benchmark he bumped up the HT speed from 400 to 800 MHz, to make a long story short, the biggest diference he got was a whooping 0.07%

So I'd be confident to say it only shows in synthetic memory bandwidth benchmarks.


Ohh and by the way, this topic sure is obscure, there isn't a single benchmark to be found on the internet, or at least not something worthy of trust (there are some reviews done by AMD themselves though)

Thanks for the update.

I have read so many conflicting reports about HT speeds. I have just bought a x4 9650 CPU and because my motherboard downgrades my HT3.0 to HT1.0 I was concerned that I have gained in one area but lost out in another.

I have read the benchmarks done by "gothitbycar" and although his tests show the HT speeds have very little affect I did notice that these becnhmarks date back to 2004 and is it possible that the demands of newer graphics cards mean that a decrease in the HT speed would cause a bottleneck?

Gigabyte GA-M57 SLI4
AMD x4 9650
2 x Nvidia 7950GT SLI
2Gb DDR800
