GeForce 6800 Ultra Preview -
Page 3 - Technology
Alright then, let's get started. First let's talk a little about the graphics core. The core itself is build upon a 0.13 Micron Process technology which is fabricated at IBM. As rumors suggested the product indeed has a lot of transistors. I personally didn't count them but NVIDIA states 222 Million transistors! *phew* Imagine all that on a 40mm x 40mm FlipChip GPU running roughly 400 MHz. And in case you are wondering yes...the transistor count is higher than a Pentium 4 Extreme Edition.
Architecture Characteristics of the GeForce 6 Series
- Pixel pipelines: 16
- Superscalar shader: Yes
- Pixel shader operations/pixel: 8
- Pixel shader operations/clock: 128
- Pixel shader precision: 32 bits
- Single texture pixels/clock: 16
- Dual texture pixels/clock: 8
- Adaptive Anisotropic Filtering: Yes
- Z-stencil pixels/clock: 32
The silicon itself is of course PCI-Express ready yet the one we are talking about is running steady on AGP8x. PCI-Express has double the bandwith of AGP8x and another plus; it allows data to be sent in both directions.
Between the lines I can tell you that NV45 will be the PCI-Express version which will use the HSI/Bridge chip. Nice gossip, I was told by an NVIDIA representative that the GPU can actually handle AGP 16x internally...now think about PCI-Express again. The 6800 Ultra is equipped with the latest available in affordable yet really fast GDD3 memory; on the 6800 Ultra it is running at 1.2 GHz (2x600 MHz). BTW GDDR3 is designed in a way that its temperature is much cooler. It's likely we are going to see 6800 cards without ramsinks.
- 222 Million transistors
- 400 MHz Core Clock
- 600 MHz memory Clock
- 256-bit GDDR3 memory
Let's review the MSI GeForce GTX 770 Gamer edition. This more affordable version of the GTX 770 might be stock clocked but is armed with military class components, an awesome TwinFrozr cooler that is very silent and keeps this GPU chilled down at a cool 70 Degrees C temperature.
ASUS GeForce GTX 780 DirectCU II OC review
We test and review the ASUS GeForce GTX 780 DirectCU II review edition. The graphics card comes with a factory overclock and an updated DirectCU II cooler that has CoolTech fans. That would be two silent 90mm fans.
MSI GeForce GTX 770 Lightning review
In this review we benchmark the MSI GeForce GTX 770 Lightning edition. Armed with military class components, an awesome TwinFrozr cooler that is very silent and keeps this GPU chilled down at a cool 60 Degrees C temperature. Next to that is has voltage monitoring points, a reactor core, a secondary BIOS as backup and liquid cooling and well, just so much more. Have a peek at what might be one of the finest GeForce GTX 770 cards available on the market.
EVGA GeForce GTX 770 SC review
In this review we peek at the EVGA GeForce GTX 770 SC (SuperClocked) edition. This model graphics card comes with a factory overclock and the new ACX cooler. Overall the card is sitting in-between the GeForce GTX 680 and GeForce GTX 780 , with its 1111 MHz core clock frequency. We take the latest games and do some FCAT testing as well.
