The NVIDIA GeForce GTX 650 Ti Review, Feat. Gigabyte, Zotac, & EVGA
by Ryan Smith on October 9, 2012 9:00 AM ESTMeet The GeForce GTX 650 Ti
Although none of NVIDIA’s partners will be selling direct copies of the NVIDIA reference design, NVIDIA did send over one of reference cards to serve as a baseline comparison (as it turns out, due to a bug you can’t underclock a GTX 650 Ti right now). Since most partner designs will closely follow NVIDIA’s reference design this actually works out for the best anyhow, as it offers a good insight into the kind of performance and design baseline we should see.
For the GeForce 600 series NVIDIA’s reference designs have been extremely solid (overclocking withstanding) and the reference GTX 650 Ti continues that tradition. The PCB itself is actually lifted from the GTX 650, which despite the difference in GPUs is pin-compatible with the GTX 650 Ti and its 128bit memory bus. This puts the length of the card at 5.75” – about as short as a PCIe x16 card can be – in a full-profile form factor. Meanwhile though taking inventory of every last electrical component isn’t practical, as near as we can tell the PCB and its components are completely identical to the reference GTX 650, which means partners are going to be able to easily drop the GTX 650 Ti into their existing GTX 650 designs so long as their cooling is adequate.
Speaking of cooling, the cooler on the reference GTX 650 Ti is a small but effective open air double-wide cooler. NVIDIA’s using a low-profile aluminum heatsink that covers roughly half the card, topped with an 80mm fan. This is the cooler style that most partners will mimic, as the 110W TDP of the GTX 650 Ti does not require a particularly large cooler; though on that note at 110W passive cooling is unlikely. As is common with open air coolers, the heatsink itself doesn’t make contact with the on-board RAM, so RAM cooling is left to airflow coming off of the fan.
NVIDIA’s RAM of choice for the GTX 650 Ti is their traditional favorite, Hynix 2Gb 6GHz GDDR5. The use of 6GHz RAM, which will be common across this family, means that the GTX 650 Ti will have some memory overclocking headroom right out of the box, memory bus willing. NVIDIA uses 4 pieces of it in a 4x32bit configuration, with 4 more pads on the back of the card for another 4 pieces for 2GB cards.
Moving on, along with losing GPU boost capabilities the GTX 650 family also gives up SLI capabilities, so unlike the GTX 550 Ti you won’t find a SLI bridge connector here. What you will find is 1 6pin PCIe power socket on the rear of the card for providing the extra power the GTX 650 needs. Meanwhile display connectivity is provided by 1 DL-DVI-I port, 1 DL-DVI-D port, and a mini-HDMI port. Since all of the Kepler GPUs support 4 displays the GTX 650 Ti can drive up to 3 displays via these connectors, and if a partner equips a card with a DisplayPort connector instead it should be possible to drive the full 4 displays off of a single GTX 650 Ti.

At 1920x1200 2gb doesn't make a difference... so when does the extra memory come into play? Is it a resolution thing or a matter of having the cores to drive it?Ryan Smith - Friday, October 12, 2012 - link
The extra memory is primarily for textures & buffers. Skyrim of course has its high res texture pack, and meanwhile you have deferred renderers like Battlefield 3 that create relatively large G-buffers, and larger buffers still if you want MSAA.ForeverAlone - Friday, October 12, 2012 - link
I don't really see why anyone would buy the 650.In the UK, the 6850/6870's are just a little bit more and massively outperform a 650.

I was surprised that 1GB is really enough for most games. I figured that 2GB was overkill, but that something in the 1.2-1.5GB would show some added benefit to more games. Is there a utility that can show just how much Ram is being used by these titles so that we know how close we are to that 1GB ceiling on most games?I think with the new consoles coming out next year, having that extra Ram on the GPU will be important for people who do not upgrade often. The new consoles should push developers to add much higher resolution textures, as well as having more variety of textures for their environments, which will no doubt push cards past that 1GB mark.

MSI Afterburner can show you gpu ram usage.Leyawiin - Friday, October 12, 2012 - link
Yes, I know the HD 7850 is a better value, so I'll get that out of the way. Still, the GTX 650 Ti with its tiny size, low power consumption and quiet operation would be great for a SFF project. Performs about on par with a GTX 560 and that's fine for 1080p gaming at good quality levels.bernlin2000 - Wednesday, October 24, 2012 - link
It's a bit silly, some of the analysis of these benchmarks. Frankly, any performance above 50 fps average is fantastic, and comparing cards above those numbers is pointless: they're all going to play those games well and nobody notices the difference between 60 and 120 fps. Saying that the GTX 650 Ti (which I just ordered) "doesn't fair particularly well" on Skyrim, when at 1650x1050 it's running at 88.8 fps is just madness. That's with the high resolution textures too? Talk about unnecessary criticism!ajay799 - Saturday, November 10, 2012 - link
i bought a MSI R7770-PMD1GD5 and its like almost silent in idle ... my 3.5 HDD is louder... and even under load its really quiet so i dont get these noise levels from the test besides one of my friends has a HD6850 and under load that sounds like a freaking jet absolutely terrible like my old GTX260 ... compared to the HD7770 thats like night and dayid say these measurements are way off...

I bought a Galaxy GTX 650 Ti 1gb for a budget build ($129 - $20 rebate) and it won't even hit 1050mhz core clock. This thing is very dissapointing
