Meet the 'reference' GeForce GTS 250
As you guys all know by now, the GeForce GTS 250 is based off the GeForce 9800 GTX+ series of GPUs. In fact it is the exact same graphics processor, the G92b. Which by itself was a respin of the 65nm GeForce 8800 (G92) series using the same silicon footprint. The difference... a smaller die-size of the graphics chipset and some internal efficiency features.
Let's have a peek at the primary features.
|Fabrication Process||55 nm|
|Graphics Clock (texture and ROP units)||738 MHz|
|Processor Clock (Shader units)||1836 MHz|
|Memory Clock (Clock rate / Data rate)||1100 MHz / 2200 MHz|
|Total Video Memory||512 or 1024 MB|
|Total Memory Bandwidth||70.4 GB/s|
|Texture Filtering Units||64|
|Texture Filtering Rate||47.2 GigaTexels/sec|
|Connectors||2 x Dual-Link DVI-I|
|Form Factor||Dual Slot|
|Power Connectors||1 x 6-pin|
|Max Board Power (TDP)||150 watts|
|GPU Thermal Threshold1||105° C - 221 ° F|
A lower die-size often equals lower core voltages, better energy efficiency and typically better clock speeds. When you understand that the G92B is based off the same chip that the 8800 GTS 512MB had, you'll also know that the GPU on the GTS 250 also has 128 shader processors to rock your games hard.
How many transistors does the NVIDIA GeForce GTS 250 have you ask? No precise data has been given, but it's safe to assume roughly 754 million transistors. The stock core frequency of the GeForce GTS 250 will run at at 738 MHz, the shader processors at 1836 MHz and the memory at 2200 MHz (2x1100) effectively. Another advantage for the GTS 250 is that you can go three-way SLI with it.

Today here at Guru3D.com, we'll review one of TwinTechs GeForce GTS 250 graphics cards. The TwinTech GeForce GTS 250 XT OC is packed with 1GB of memory, pre-overclocked and comes with a wicked cooler from Arctic Cooling. For a first introduction... that was impressive to see. But will the product be able to keep up with Guru3D's pace in testing? Let's find out.
