OpenCL: GPGPU Benchmarks
Unlike the proprietary CUDA and APP APIs, OpenCL is platform-agnostic, presenting developers with a common base for creating applications optimized for parallelized architectures. Specifically, GPGPU is becoming more and more popular, since programmers now no longer need to code for a specific piece of hardware, but rather for the API, with the driver handling the rest. Gaming prowess aside, not all cards are created equal in terms of GPGPU performance, and so we’ll take a closer look at how the GeForce GTX 650 Ti stacks up against the competition, both old and new.
Of course, the most interesting comparison comes from comparing Nvidia's latest to its direct competitor, AMD’s Radeon HD 7850 with 1 or 2 GB of memory. Additionally, we are also evaluating how the various factory-overclocked GeForce GTX 650 Ti models behave at their respective clock frequencies. We are purposely not including the Radeon HD 7770 and GeForce GTX 650, since the GTX 650 Ti is meant to round out Nvidia’s mid-range family, while setting itself apart from these smaller models. Let’s see whether it succeeds.
As expected, AMD’s Radeons lead the pack when it comes calculating SHA-256 hashes. If you’re into bitmining, then none of Nvidia’s current- or past-generation cards are a good fit, and that applies to the GeForce GTX 650 Ti as well, even if you factor in its lower power consumption.
As comparisons with the factory-overclocked GeForce GTX 650 Tis show, performance scales practically linearly with clock frequency.
Once again, we're using LuxMark 2.0's slightly simpler scene for testing. Otherwise, the bars representing the GeForce GTX 650 Ti would have been nearly imperceptible. We see performance scale based on clock rate once again, and AMD's Radeon HD 7850 remains far out of reach.
PostFX combines OpenGL and OpenCL into one demanding workload. Although this benchmark comes directly from Nvidia’s own SDK, it also serves to demonstrate how quickly performance can shift with the introduction of a new architecture, such as AMD’s GCN.
The NQueens problem is the sole ray of light for the Nvidia cards here, and the GeForce GTX 650 Ti is finally able to beat out AMD's Radeon HD 7850.

Awesome, finally something that mainstream budget users can afford from Nvidia, been waiting for ages!Reply
40% slower than the 7850 while costing 10-20% less, and 10% faster than the 7770 while costing 25% more.Reply
That looks like a fail to me, and don't even get me started on how late this is.
Would be awesome if you would include HD 5770 in benchmarks vs this one too, sure its old card but would love to see how powerfull is that one compered to this one.Reply
Why would you not include the GTX 660 Ti in the tests? After all, the 650 Ti and 660 Ti should be the options of the day for upgrades - why not compare them?Reply
nVidia, you really need to stop gimping your bandwidth!Reply
Seriously, such a waste of silicon that could perform quite a bit better if you just gave it a little more breathing room....
I assume the place where it cripple the 650TI is the 16ROP as well as the 128bit bus. But the 16ROP is probably the biggest bottleneck of the card, this is the only place where u cant be fix by any OCing at all.Reply
With 128bit bus, they could have just leave the memory speed @ 6GHz. 5400 is pretty much ruin the thing.
Edit: btw, this is probably one of the most useful review I see for a while. 6870/6850/560/460/7770 are all there, with benchmark of AA on and off. thumbs up for u author!

The HD7850 and GTX 650ti are essentially the same price on New Egg.
another PhysX card I suppose..Reply
slightly too weak for a dedicated in my book.
I said my book as in my opinion.
Mike-THWhy would you not include the GTX 660 Ti in the tests? After all, the 650 Ti and 660 Ti should be the options of the day for upgrades - why not compare them?Reply
Because comparing cards in the ~150 dollar range to a card thats +280 dollars is asinine?
AnandTech has already released an article covering AMD officially dropping the price of the 1GB 7850 to $169 for the fall seasonReply
This means we will easily see $150 or less after rebates and officially makes this Nvidia 650ti product a total fail. I see no reason to purchase this.
