G92 Terbaru: 8800GS

[VERRY]

Nvidia merencanakan akan meluncurkan 8800GS sebagai pengganti card kelas mid end sebelumnya yaitu 8600GTS. dengan dibekali memory yang sebesar 384MB, interface memory 192bit, dan SP sebanyak 96. sepertinya performa dari card ini akan berada jauh diatas 8600GTS tetapi tetap berada di bawah 8800GT.



harga di untuk card ini diperkirakan adalah $149-$179, bila melihat harganya maka saingan terberat card ini adalah HD3850 dari Ati. tetapi tentu saja itu merupakan harga perkiraan, bisa saja setelah card itu diluncurkan dipasaran maka harga bisa berada di atas harga yang saya sebutkan tadi.

192 bit..kok nanggung yah..

Sama 3850 bagusan 3850 kan ya..?

blom tau lah, keluar ajah blom

i'll tell you something...

arsitektur memory interface di G92 tu make 4 cluster
yang masing-masing cluster adalah 64bit

klo memang mau di sunat ... jadi 3 cluster, ya itu bisa aja
64x3 = 192

tapi kok janggal ya
128bit dan atau 256 bit saja kali ya

we'll see

aneh 192bit

kalo ada 88gs, 86gts kemana donk?

^ dibawahnya...

ok ... dapet rop, tmu, core/shader/mem

Nvidia is gearing up to launch another GeForce 8800 graphics card—the GeForce 8800 GS 384MB—in the very near future if rumours are to be believed.

The new card will be based on the same G92 graphics processor that’s at the heart of both the GeForce 8800 GT and GeForce 8800 GTS 512MB cards that were released towards the back end of last year.

The GeForce 8800 GS will probably be clocked at 575MHz core, 1438MHz shader and 1700MHz memory. Of course though, clock speeds only mean so much these days, as a modern GPU is an incredibly complex piece of silicon.

What Nvidia looks to have done in order to create the GeForce 8800 GS 384MB card is to simply disable two of the shader clusters in G92—there are at least eight inside—to leave 96 stream processors.

Because the texture units are allocated on a per-cluster basis, these have also been reduced – there are now 48 units for both texture filtering and texture addressing.

The card will also feature just twelve ROPs, meaning that there will be a 192-bit memory interface that connects the GPU to the 384MB of GDDR3 memory.

Being based on G92, it supports PCI-Express 2.0 and will feature Nvidia’s second-generation video decoder. What it won’t feature though is support for DirectX 10.1 – that’s not a huge issue, as even AMD says that DX10.1 won’t ever become a minimum specification, but there are some nice improvements in the updated API.

The guys at Expreview claim to have the first benchmarks of the new product and you can find them here. Overall, the GeForce 8800 GS appears to be around 25 percent slower than the GeForce 8800 GT, but the new card’s price is likely to fall more in line with the Radeon HD 3850. What a coincidence...

core: 575MHz
shader clock: 1438MHz
mem ddr rate: 1700MHz
192bit
96 Stream Processor
12 ROP
---> TF dan TA??
klo G92-88GT dapet 7 cluster. 16 blok --> 112SP; dan 8 addressing --> 56TA/TF
saya pikir 8800GS ini dapet 6 cluster. 16 blok jadi 96SP; dan 8 addressing --> 48TA/TF

hanya mencoba meramal kalkulasi GPU


Shader Arithmatic
- 2 flops dan 1 flop co-op
- 96SP
- 1438MHz shader clock
-----> 96 * (2+1) * 1438 = 414GFlops


Pixel Fillrate
- 12ROP
- core: 575MHz
---> 12 * 575 = 6.9GPixel/s


Texel Fillrate
- 48TF/TA
- core: 575Mhz
--> 48 * 575 = 27.6GTexel/s



Memory Bandwidth
- 192bit
- 1700Mhz DDR
--> (192*1700)/8 = 40.8GB/s







sepertinya 8800GS 384MB bakalan menyerang HD3850 both 512MB and 256MB
