NVIDIA GeForce GTX 650 Ti Round-Up: EVGA, ZOTAC, GB

Article Index:   

NVIDIA has been on a tear as of late, releasing a constant stream of GPUs over the last few weeks. In mid-August, the GPU giant released the GeForce GTX 660 Ti and less than a month later, followed up with the GeForce GTX 660 and GeForce GTX 650. Here we are now, less than a month since that release and NVIDIA is at the ready again with yet another new GPU called the GeForce GTX 650 Ti.

As its name implies, the GeForce GTX 650 Ti is a step up from the standard “non-Ti” GeForce GTX 650. The new GeForce GTX 650 Ti, however, isn’t powered by the same GPU as the GTX 650. Whereas the GeForce GTX 650 has a GK107 GPU at its heart, the new GeForce GTX 650 Ti uses the same GK106 as the higher-end GTX 660 series cards, albeit with a few blocks of the chip disabled. The end result is a card that’s much more powerful than the standard GeForce GTX 650, but is priced only slightly higher.

Take a gander at the specifications and reference card below and we’ll follow up with a look at a trio of custom GeForce GTX 650 Ti cards from a few of NVIDIA’s board partners and a full performance profile on the pages ahead…

Like the GeForce GTX 660, the new GeForce GTX 650 Ti is based on the GK106 GPU. Although the GK106 features all of the same technology as NVIDIA’s more powerful Kepler-based graphics processors, this GPU is somewhat smaller and scaled-down versus its higher-end counterparts.

GK106: GeForce GPU Block Diagram (Note - One SMX is Disabled on the GTX 650 Ti)

Here is a high-level block diagram of the GK106 GPU powering the GeForce GTX 650 Ti. The actual chips are manufactured using TSMC’s 28nm process node and are comprised of approximately 2.54B transistors. In its full configuration, the GPU features three Graphics Processing Clusters (GPC) with three SMXs and a total of 960 CUDA cores arranged in 5 SMXs. There are also 80 texture units and 24 ROPs within the GPU, along with 384K of L2 cache. On the GeForce GTX 650 Ti, however, one of the SMXs has been disabled, which results in a total of 768 active CUDA cores, with 64 texture units, 16 ROPs and 256K of L2 cache.

A memory partition on the GK106 has also been disabled on the GeForce GTX 650 Ti. Instead of the GTX 660's 192-bit interface, memory on the GTX 650 Ti is linked to the GPU via a 128-bit interface. In comparison to the GeForce GTX 660, the new 650 Ti has less cache, a narrower memory interface, and fewer CUDA cores, texture units, and ROPs, which results in lower compute performance, fillrate, and memory bandwidth.

Some Pics of the NVIDIA GeForce GTX 650 Ti Reference Card.

NVIDIA’s reference specifications call for a base GPU clock of 928MHz on the GeForce GTX 650 Ti, 1GB of memory, and memory clock of 1350MHz (5400MHz effective). At those frequencies, GeForce GTX 650 Ti card will offer up to 86.4GB/s of memory bandwidth and 59.2GTexes/s of textured fillrate. Many of NVIDIA’s partners, however, are ready with factory overclocked models (which we’ll show you on the next page), that will offer somewhat higher performance characteristics. Many cards from NVIDIA's partners will also feature 2GB frame buffers, instead of the 1GB of the reference card.

The GeForce GTX 650 Ti has a TDP of 110 watts and requires a single, supplemental 6-pin PCI express power feed. Cards are two-slot wide, but sport a short 5.65" PCB. The output configuration consists of 2 x DVI outputs and 1 mini-HDMI output, but the GPU supports up to four independent displays, so some parts may release cards with four outputs as well.

The performance is good considering the lower cost.

The design of the card isn't complex for the same reasons,...........lower costs.

ha哈Big SmileHello Finally someone back to me Good fun You are my first contact with foreigners Online It's nice meeting you I can't understand English Because I'm Chinese Is computer hardware enthusiasts Want to know foreign friends I do not know these words are not wrong Please forgive me Looking forward to your reply 哈哈

I don't know Chinese either. I just used Google to translate your comment. Welcome to our website.

I like the EVGA and Gigabyte brands a lot. Not so much Zotac.

These GTX650Ti cards are good performers for the money, but they don't have an SLI connector on them. That is why I like the GTX-660 and GTX-660Ti better.

EVGA Relatively rare in China Gigabyte many I use the GTX650ti of GALAXY brand  I wanted to buy MSI models GTX650ti But have not yet listed Obviously, MSI work better China has more second-tier brands Is its own brand Features work in general Selling price is relatively cheap Indeed true Mid-range graphics cards without SLI Unfortunately How much your GTX650ti price? We here Price 1000rmb That is, $ 160 Finally, want to say that our ability to communicate through chat software? For example, do you use msn is not it? I can register and talk to you Thank you very much

We can get the EVGA GTX-650Ti for $146.82 (916.3770 RMB) with free shipping provided, here in the US.

We like the EVGA brand because they offer a lifetime warranty on products that they sell. Also, they have a "trade-up" program that let's you use the card for 30 days and return it to buy a better card, with a full refund towards the newer card's purchase.

NVIDA cards enjoy better driver support for differing operating systems too.

Really good to hear you say Here there is no lifetime warranty This provides a two-year warranty Asus Gigabyte MSI warranty of three years You can also use 30 days for better It seems there is difference!  We work good graphics card prices and relatively high  

In China Less self-developed graphics motherboard manufacturers Many of which are Taiwan OEM Paste their own brand sales Quality and after-sales did you EVGA Big Smile

Your work, what is it?  Also like computer hardware? Can add you msn chat with me?

Google translate is all I have that works.

I do not do MSN chat,....sorry.

As long as the local knock-off companies build a good board, then it's a good thing.

I have PNY, XFX, and ASUS GPU's here now. I am saving for a pair of EVGA GTX-660Ti cards now.

The two XFX cards are Radeon 7770s and they are in Crossfire. The ASUS and PNY cards are both GTX-570s and are in SLI.

I use them to game with mostly. (First Person Shooters)

I do a little video encoding too. The Radeon 7770s are good, alone in a system, but in crossfire, they give much better performance. It was worth it to do as I see it.

The GTX-570s are quite good alone, but they're fantastic in SLI. The GTX-570s are in a i7-2600K system and the Radeons are in a FX-4170 system.

Both perform well and are fun to game on.

This might be a nice upgrade to my 3 year old GTS 450.
