1800 GFLOPS? Its not a Tahiti core if it cut back that much. The 7970 has 3800 GLOPS, but GFLOPS means nothing in gaming. It should be a customised core, but its not Tahiti if it doens't have at least 112 texture units, if it as 80 its a Pitcain card. If its 40 its Cape Verde. And if they put a Cape Verde card in, Sony fails. Need at least 60 texture units for next gen.

By comparison, RSX does 0 GFLOPS (no unified shaders) and has 24 texture units (gimped by 128-bit GDDR3)

I understand that. The way I read the specs in the OP. It seemed to indicate that the PS4 would have CPU, APU, and GPU. I was under the impression that the PS4 was going to have APU and GPU. With the GPU on the APU working in concert with the independant GPU to enchance performance.

actually the RSX is 400.4 GFLOPS, while it's not really a meaningful spec in graphics performance but in the same GPU generation it can be used for relative performance. 

Prices should go way down by the time it goes into production in late 2013/early 2014. Also AMD would most likely sell them to Sony at a much lower price than retail since they'll be using millions of these.

Hybrid/Asymmetrical Crossfire would probably yield the most bang for buck performance-wise. 

Do you really think Sony pays retail price though, I'm sure they get it much cheaper since they will be making the company billions of dollars.

You make a very good point. People have no idea how much Video Cards get marked up at retail. That's not even taking into account the price they'd get for buying in bulk. Although my biggest concern would power usage and heat dissipation.

Nah, it'll be much cheaper. It's bought in massive bulk and coming out in 2013, so more lke $100-150 I'd say

These specs looks great.

You don't need 4xaa at 1080p, so dial that back to 2xaa, factor in it being a closed system and optimized for and all and it'll do BF3 on ultra @1080p + 60fps no doubt.

About the GPU, as Gilgamesh said, what the RSX chip is based on was about $400 in 2005, and that definitely isn't what drove the PS3's price up. Sony will also buy in bulk and this is a 2013 console, so that price will be drastically reduced by the time it's in the Orbis.

Also, if this rumour is true, and they go for 4gb, my prediction was fucking accurate! CPU is almost there, though that's obvious, GPU is spot on, RAM is correct (almost), HD is almost spot on! Though I didn't predict any flash memory.
