AM2 and DDR2 800 not crackin it

post #1 of 20
Thread Starter 
they are seeing only a 3-5% increase with these new processors and ddr2 800 memory...

I hope amd comes up big and suprises us all read about the recent look into AM2..

I think that AM2 itself is not suppose to be a performance booster, but rather open the doors for new processors and memory standards that do have performance boosts. Thats my

I knew the move to DDR2 was not going to help one single bit.

Why? Well, there will never be DDR2 800 CAS 2-2-2-5.

HyperTransport and DDR2 don't go hand in hand, I saw that when the performance and overclocking ability of an nForce 4 started to show up here in the forums.

If there was no improvement from DDR 400 to DDR2 667, why would a lot of people speculated that DDR2 800 was going to be better? Beats me!.

If DDR2 800 is not that much of an improvement, why the hopes of DDR3?
That ICM and hypertransport need to be heavily revised.

Though I woulnd't be surprised if I see AMD + RAMBUS, Z-RAM anyone?

The thing is that there is a real latency raise when the cpu memory controller moves to write to the DRAM and DDR2 dram will not be very beneficial to AMD for the reason of stall awaiting write.

AMD did not move to DDR2 for performance. This was done to placate the DRAM manufacturing companies so that they did not have to continue creating two fabs for DRAM. When DDR is obsolete with regards to new motherboards then there will be singular DDR2 Fabs. Secondly, the decision was to impliment DDR2 to negate Intel using it as a selling point.

Intel's legacy Northbridge memory controller will see a far greater advantage from DDR2, especially when the DDR speeds increase and latency decreases.
Now DDR always has a write latency of 1T and this surely benefits an onchip memory controller. This time is dictated by the JEDEC specification and cannot be changed. For DDR2, this write latency depends on the read latency and equals write latency minus one clock which does not benefit AMD's onchip memory controller as in comparison to 1 clock for DDR this is a lacking feature and is at this time the most basic drawback to DDR2. This is heightened with an AMD processor for which the request control is strapped to the onboard memory controller at such a low speed (in comparison to the read latency of that controller) thus creating a read/write stall.

On the legacy Intel Northbridge this latency is already as the move is from processor to dram with the concurrent latency drop anyway.

754 isn't any worse than 939 except for no dual core procs....

AMD needs new architecture to take full potential of the DDR2 memory, their using really old achitecture which with DDR2 800 and only 3-5% boost isnt really suprising, Intels gonna get the lead soon, especially with Conroe coming, hopefully AMD pulls something big off this year

Just my 2 cents

intel is gonna take the top with conroe
but it will be expensive

and AMD will still reign on DDR

it will be a while till DDR disappears,

Umm on the contrary.

Conroe priced from $180 to $475 ($475 being the E6700 that stomped the FX60) and the XE (E6800 3.33Ghz) will be about $800. That is A LOT cheaper than anything else at it's performance, considering the $180 Conroe will beat ANY current P4 out there.

Ok guys, this is an overclockers forum, you think any of us are gonna settle for ddr2 800? I want to know what am2 looks like oc'd 1:1 with ddr2 1000!
