Nvidia had recently announced the launch of their kepler based dual graphic card which will be as usually be called as GTX 690. It’s performance and other benchmark data is already available online because of the Nvidia’s Geforce Webcast in Shanghai, China.
Architecture and inside GTX 690
- GTX 690 basically consist of two fully blown GK 104 cores.
- This is the same core which is featured in GTX 680 also which holds the title of world’s fastest discrete graphic card presently.
- Specs include –> 1536 * 2 CUDA cores, 256 CTU’s, 64 ROP units which is basically double of the single GTX 680 GPU.
- GTX 690 uses Nvidia’s custom designed PLX switch rather than NF200 bridge which was used in their GTX 590 GPU for linking two on board chips in dual GPU.
- NF 200 is limited only to PCIe 2.0 generation whereas PLX switches from Nvidia is compatible with 3rd generation PCIe technology also.
- The new GTX 690 also features 256*2 bit wide bus and a bandwidth of 192 GB/s per chip.
Power
- Well, low power consumption is one of the key features of Nvidia’s Kepler series and because of this GTX 690 has much lower TDP of 300 watt as compared to GTX 590.
- Due to lower power consumption, Nvidia has to down clock the cores of GTX 690 to 915 MHz.
- It has two 8 pin power connectors which delivers power of 300 watt and PCIe slot delivers 75 watt also. So this makes 375 watt in total.
External of GTX 690
- Here we can see specially designed chromium plates aluminium body for the GPU.
- Two vapour chamber on each GPU same as in their previous dual GPU’s
- Fan is located at the centre and is made of magnesium alloy for faster heat dissipation.
Ports
- GTX 690 have 3 Dual link DVI ports and 1 mini display port which can support in total 4 simultaneous displays.
Pricing
- This card is not yet launched to public but when will it be launched is still not fixed.
- Indian launch of this GPU is also not confirmed. Irrespective of the fact that one cannot even find other kepler based GPU in local shops here.
- GTX 680’s price floating around Rs. 30,000. So companies will price GTX 690 around Rs. 50,000
