Big image of my 4870 that I took on my phone camera.
That looks like the same score as a vanilla HD4870..
I sure hope that's not a real score, or that it was taken with a weak setup.
4890 center resistors: 4x11
4870 center resistors: 6x12
that said the entire resistor arrangement outside the center of the GPU area is %100 different between the 4870 and 4890. I find it hard to believe all that change is for power consumption alone....
Is it possible they are hiding 40nm from us?
well purely area wise (resistors behind the gpu) there is a really significant size difference...
the 4890 is 44 units and the 4870 is 72units
.72(ratio 40:55nm) --> .61(ratio 4890:4870)
You were not supposed to see this.
Since when have they started to mark resistors with a "C", instead of a "R" on the silkscreen?

Faster clock to clock than the RV770
We’ve heard that ATI's secret weapon with RV790 is not actually the higher clock speed, but rather improved shader efficiency, which enables it to do things a bit faster than a RV770.
This would mean that the RV790, Radeon HD 4890 card should end up faster compared at the same clock and specification to HD 4870 card.
We are not sure what ATI did to its shaders, but this is the reason why RV790 chips are actually differ from the RV770, and that the pin count is not the same. The release day should be April 6th.
The only way to avoid disappointment would be to close oneself in a hut in the Arctic until April 6th...everything else is speculation.

Google for "surface mount ceramic capacitor".
Among the nigh-random images you'll spot these.

who cares about the difference between resistors and capacitors, lets just make more rumors about this awesome new, non-re-badged ATI card.
Has anyone seen this thread yet? Shows some preliminary results which are taken with a grain of salt.

I honestly don't believe they are. Here are my 4870 results using a E8400 @ 3.60Ghz
In all honesty, using a 920 should have yielded a higher result, 3D06 is CPU Bound.
