NVIDIA's D9M makes its first appearance on corporate roadmaps

NVIDIA's newest mid-range processor, codenamed D9M, will make its official debut as the GeForce 9600 GT.

Corporate guidance from NVIDIA lists the initial GeForce 9600 GT shipments come stock with a 650 MHz core clock and a 1625 MHz unified shader clock.  Unlike the G84 core found on GeForce 8600 GT, D9M will feature a 256-bit memory bus interface.  Coupled with a 900 MHz memory clock, NVIDIA calculates the memory bandwidth at 57.6 GB/s. 

The texture fill rate is estimated at 20.8 billion pixels per second.  The company would not indicate how many shaders or stream processors reside on the D9M core. 

Late last year, NVIDIA confirmed the D9 family will use TSMC's 65nm process node.  The company introduced its first 65nm processor shrink in November 2007: the G92

Other details of the D9M family have already surfaced.  ChileHardware published slides yesterday claiming the GeForce 9600 requires a 400W power supply that requires 26A on the 12V rail.  Unlike previous mid-range GeForce cards, the D9M will require a 6-pin supplementary power connector.

NVIDIA publicly confirmed other details of D9M: DirectX 10.1 support, Shader Model 4.0, OpenGL 2.1 and PCIe 2.0 support just to name a few. 

Further documentation from NVIDIA claims the 9600 GT will also support the Quantum Effects physics processing engine. 

Like all NVIDIA processors, the GeForce 9600 is also HDCP compatible, though final support still depends on vendor implementation. 

NVIDIA declined to comment on expected price of GeForce 9600.   A representative for NVIDIA would comment that the performance increase between GeForce 9600 and GeForce 8600 is "almost double."

If the performance of a 8600GT -> 9600GT is almost doubled, then this card will be a pleasant addition to their family. As long as it is priced right.

What I'd like to know is how the 9600GT will stack up against the G92 (8800 GT)

I am sure the MSRP will be reasonable, the bigger question is how high will retailers raise that price should the demand be high.

That all depends on if it competes with G92. If it does, then factory-overclocked D9Ms will likely be a lot more popular than stock G92s, in turn driving the prices of factory-overclocked D9Ms up, and stock-clocked G92s down.

The real thing to watch for here is the price. Assuming G92 stays around its current ~$275 price point and D9M comes in anywhere below that (with the performance difference much less than the price difference), Nvidia may be obsoleting its own lineup again.

9600GT will be very close to 8800GT in lower res.
it will trail behind faster in higher res.

They both have more or less same (8800GT,9600GT)

Membandwidth 57.6 GB/s
memory bus 256-bit
Core Speed MHz: 600,650
Memory Speed MHz: 900 (1800 effective)
DirectX / Shader Model DX 10,10.1 / SM 4.0

however, 9600GT's texture fill rate is low (20.8 bp/s) compared to 8800GT's (33.6 bp/s).

now, it all depends on Stream processor count. but i doubt 9600GT can even get close to 8800GT in higher res.
