DDR2 vs DDR3 - ASUS Blitz Formula vs Blitz Extreme...CellShock Rams involved...

[hipro5]

Guys don't take a look at the "only" 1 - 2 % more performance.....Here is XS and (at least) all of us are trying for the max if this is on air/phase/cascade/LN2....

On 2k3 with the DDR2 Formula with CrossFire @ 850/950 at 3950MHz, I did ~70700marks
With the DDR3 Extreme at ONLY 823MHz Ram-speed, I did ~72500MHz

On 2k5 with the DDR2 Formula with the same clocks on CF, I did ~25600marks...
With the DDR3 Extreme at the same, I did ~26000.......

So as for me, yes it worths it......
.....and as I said, matching the DDR3 with an X38 chipset and with pure 2 x 16 PCI-E, we will see quite good differences as for 3D and games.....

Though at this point I HAVE to be honnest and say that the ABIT AW9-MAX with the 975 chipset, STILL CAN'T be catched as for the 3Ds......
Maybe because it uses 2 x REAL x8 PCI-E when on the other hand the P35 chipset on ASUS Blitz (Extreme or Formula) uses a "chip" to "break" the x16 PCI-E to 2 x 8 PCI-E......This might have some latencies to the Northbrigde so that's why I get better numbers with the 975 chipset....

The Memory bandwidth with the Extreme DDR3 can't be touched easy though.... BUT the VERY LOW latency on the 975 chipset, makes it fast enough to beat anything out there as for 3Ds....

Example:

3DMark2005 at 3950MHz and CrossFire at 850/950

ASUS Blitz Formula: ~25600marks
ASUS Blitz Extreme: ~25994marks
ABIT AW9D-MAX: ~26422marks

2k3 with the 975 was ~73200marks

975 chipset was running at only 439MHz fsb, rams 1:1 with Cas 3-3-3-4....

As I see, 975 STILL rules in 3D till X38 comes out.....
