Thumbs up Nvidia's 40nm GT212 to have 384 SPs, 96 TMUs, and 256-bit 7Gbps GDDR5

Nvidia's 40nm GT212 to have 384 SPs, 96 TMUs, and 256-bit 7Gbps GDDR5



half-step between GT200b and GT300


by AuDioFreaK39

According to a recent report from Hardware-Infos, the specifications of Nvidia's coming flagship 40nm GT212 architecture have been identified and revealed from unnamed sources near Nvidia, as usual. To start matters off, GT212 is the successor to 55nm GT200b which is currently rolling into production. In comparison, the upcoming architecture is essentially following two similar footsteps of 65nm G92 last March - a die shrink to a smaller fabrication process and a decrease in memory interface width.

Can someone explain why it will only have 256bit memory interface though?

The higher bandwidth provided by GDDR5 offsets the need for a wider bus. Simpler design means lower manufacturing costs for nvidia as well. That's the basic reason.

Well a 4870 clocked at 7Gbs @ 256bit bus gives a memory bandwidth 224 GB/sec . I dunno how close that will resemble the GT212 due to completely different architectures. If these rumors are correct thank god for AMD's 4800 series competition, competition = lower prices and faster innovation.

Can't wait for some Core i7/new GPU action this summer.

Will this be cheaper than the current cards like the GT260? Sub $200?

Probably a $400 launch price or so since this will most likely be the high-end part. Maybe a ~ 280 SP card at a $250-300 point?

Think it's meant to compete with the upcoming 4800 successor, which would put it around 200-300$. The simpler design and die-shrink suggests a lower price as well.

Bring it on!!!!!

Looks very good:

60% shader increase
40nm, high clocks?!
200+ GB/s bandwidth?!

In couple years Nvidia and ATI will make cards with 512bit wide bus + GDDR5 which will give some insane amount of memory bandwidth and probably free AA 4x.
