Great website for X1400 to 7900GS - Page 2

Is this website completely accurate? I'm pretty sure the 6800go Ultra had different clocks than the 6800go.

Anyways,
pdonket, how did your original laptop get damaged beyond repair anyways?

Mine didn't end up ever really getting damaged, it was that I had an overheating problem with my processor and for some reason, no matter what they tried, it refused to stop overheating so my system got replaced due to a helpful tech

Yes the core/mem speeds are the same for both.

the difference lies in the memory interface. The 6800 is a 128/256 bit hybrid, where the 6800 Ultra has a full 256 bit memory interface.

Then why was the TDP so much higher for the Ultra?

huh? The vanilla and ultra aren't clocked the same. The ultra supposedly used handpicked vanilla cores though to be able to oc heavily (not to mention that 1.38 V ). They do however have the same amount of pipes and shaders but the 6800go is ddr1 whereas the ultra is ddr3

What it doesn't say is that the Vanilla had a 128/256 bithybrid memory interface that degraded the performance of the card.

Now let me clarify,the clock speeds of the GeForce 6800 Go (non-ultra) will vary depending on the actual notebook vendor, but there are two basic configurations: 300/300 and 450/600 (core/memory). The difference in the two configurations mainly boils down to the type of memory used - DDR1 or DDR3, with the faster configuration being a DDR3 one.

The question asked earlier was regarding the Chart comparison that showed the 2 units listed.

I'm not gonna go as far to say that the 450/600 6800go doesnt exist but I just find it unlikely...I've never heard of it except when the original 6800go first came out...It seems as if this projected 6800go became the ultra imo...It just doesnt make sense to me to have a 6800go released with the same clocks as the ultra...they share the same core meaning they'd be pushing the same voltages and so on...what would be the advantage of picking one over the other? Of course nvidia could've been leading us on but they supposedly handpicked the cores for the ultra meaning a run of the mill 6800 core could not operate under the ultra's conditions...to finish my rant, I'll just say I'll believe it when I see it...

Pdonket, perhaps you should take a look through your thread & post a culmination of all the links on this page that are worth linking to in your first post so people don't have to scan through the entire thread for all the info.
