Today we are checking out Nvidia’s new GeForce GTX 650 Ti graphics card based on the GK106 architecture. Just last month we saw the arrival of the first GK106 based graphics card, known as the GTX 660, and now it is time to take a look at the sub-$200 version...
Nvidia finally released their $300 current generation part back in August when they unveiled the GeForce GTX 660 Ti based on the GK104 architecture. This new graphics card offered a performance to price ratio that was unmatched by any current generation product, including Nvidia’s own GTX 670.
Consequently AMD was forced to reduce pricing across most of their Radeon HD 7000 series in order to better compete with the GeForce GTX 660 Ti. Then a month later along came the $230 GTX 660 based on the GK106 architecture which was, according to our results, on average 14% slower than the Ti version.
This again meant that the price vs. performance had been improved as the non-Ti version was just 14% slower yet roughly 23% cheaper. When compared to the competition from AMD the GeForce GTX 660 again faired quite well delivering 10% more performance than the Radeon HD 7850 ($200) and just 5% less than the 7870 ($250).
Having successfully hit AMD with a current generation $300 product in August and then a $230 product in September, Nvidia is now delivering their sub-$200 product this month as they ready the new GeForce GTX 650 Ti.
The GeForce GTX 650 Ti is targeting the $150 price range, making it roughly 35% cheaper than the GTX 660. At this price it is around 30% more expensive than the Radeon HD 7770 which typically commands a $130 price tag.
What’s interesting about the GeForce GTX 650 Ti is that it is based on the same GK106 architecture as last month’s release, the GTX 660. However while they might share the same Kepler GPU codename they are very different. The GTX 650 Ti has of course been downgraded, at least on paper, featuring one less SMX Unit and as a result 20% less CUDA Cores. The TMUs have also been reduced by 20% while there are 33% less ROPs.
The GTX 650 Ti’s GPU has 768 CUDA cores (192 less than the GTX 660) meaning there are 4 SMX. The TAU count has been reduced to 64 from the GTX 660’s 80, while the ROPs have been reduced from 24 to just 16.
However Nvidia didn’t stop there, cutting the 192-bit memory bus of the GTX 660 down to a 128-bit bus for the GTX 650 Ti, which in turn has reduced the memory bandwidth to just 86.4GB/s from 144.2GB/s, a 40% reduction. This has had many questioning if the GeForce GTX 650 Ti is going to be worthy of the $149 price tag and today we plan to find out...
