Guess the transistor count.

How big is that coin? Like... what dimensions?

[gram_vaz]

lol, that pic means nothing to me as i don't know what the size of that asian coin is.

[Smurfie]

About 0.75 inches in diameter.

[GlowStick]

Wow, nice spy photo. Hmm, honestly looks a tad smaller than the G70, however with .90 process it may be around the same count.

[anzak]

I'm gonna say 350 million transistors.

[shabby]

375 mil :)

[rohit]

280 mil.

[Roadhog]

400mill

[superklye]

One hundred beeellion dollars! mmmmyeahahahaha *puts pinky to mouth*

So is this the 3% yield chip or the less than 1% one? :confused:

[tristancarton]

chips would be the same size. they would just have pipes locked or turned off. (i.e.-32 pipe design with 0,8, or 16 pipes turned off will all have the same die size)

That pic is too dark to see the core details so I bright it up a little...

Now that much better. :D

I guess it around 23.4mm.

I dont got a clue when the chip was manufactured.

Here is my attempt.

All I can make out of it is "R520" and "Taiwan". Which isn't anything new, but at least we know for a fact that its really the R520.

EDIT: Added some image sharpening

[AthlonXP1800]

I collected all R520 pics and worked out the details on the core, I got it all right but I couldnt make out the third line, it hard to figure out so I guess it W50598.00.#20.

Fewer than the G70? Since its a 90nm part and looks to be about the same physical size as the G70, it should have more transistors.

[coldpower27]

That core actually looks smaller then G70 to me. Though that should be the case as it is on the 90nm node.

[mikechai]

My take 300M (bear in mind ATI counts transistors differently)

[rohit]

So is this the 3% yield chip or the less than 1% one?
Doesnt Matter, Its one of the RARE ones. You pay for one now, and Ati will pay you 100times more, after some years.. Its sure a collection item.

EDIT: Looking at the past, ati VPU's always have had lesser amnt of transistors than nv counterparts. so i guess this will follow the trend, so sumthing around 280mil is my guess.

[RpPRO]

299 m. :D

I seem now know the R520 size numbers after read Xbit Labs news (http://www.xbitlabs.com/news/video/display/20050822210504.html) that R520 is very similar size as R480 core.

Let see...

NV40 on 0.13 micron use 222M transistors and G70 on 0.11 micron use 302M transistors, to work out how to add up 222M to 302M figure. The size difference between NV40 0.13 and G70 0.11 is 20% = 44.4, then round to the nearest number which is 40 then 2 times that and make it 80M transistors and add it with NV40 222M transistors = G70 302M transistors. :D

R480 on 0.11 micron use 160M transistors and R520 on 0.09 micron use very similar size as R480, the difference between 0.11 and 0.09 micron is 20% = 32, that mean R520 have 60M transistors more than R480, that total of 220M transistors.

R520 have 220M transistors on 0.09 micron, that the same transistors size as NV40 on 0.13 micron. :eek:

If we use that logic, then the r520 is simply a 16pipe card with sm3 probably running at some insane mhz.

I'm sorry. I thought everyone here was talking out of there hindquarters. :o
