Gigabyte GeForce GTX 650 Ti (GV-N65TOC-2GI) Video Card Review
By Gabriel Torres on October 9, 2012


Introduction

The new GeForce GTX 650 Ti is the latest GPU from NVIDIA, targeted to video cards on the USD 150 segment. The Gigabyte GV-N65TOC-2GI comes overclocked, with 2 GB of GDDR5 memory instead of 1 GB and a better cooling solution than the standard model. Let’s see how this model from Gigabyte fared on our tests.

At USD 150, the new GeForce GTX 650 Ti is the quintessential mainstream video card, targeted to users who want to buy a good video card but don’t have the money to spend on a more expensive model. It comes to replace the GeForce GTX 550 Ti, and its main competitor is the Radeon HD 7770.

The new GeForce GTX 650 Ti uses the PCI Express 3.0 interface, similarly to its main competitor, while the GeForce GTX 550 Ti, which we also included in our comparisons, uses the PCI Express 2.0 interface. Differently from models starting with the GeForce GTX 660, the GeForce GTX 650 Ti doesn’t have a dynamic overclocking feature.

In the table below, we compare the main specifications for the video cards included in our review. The prices for the Gigabyte GV-N65TOC-2GI, the GeForce GTX 550 Ti, and the Radeon HD 7770 were researched at Newegg.com on the day we published this review and do not include rebates. The price for the GeForce GTX 650 Ti was provided by NVIDIA.

You can compare the specs of these video cards with other video cards by taking a look at our “AMD ATI Chips Comparison Table” and “NVIDIA Chips Comparison Table” tutorials.

Now let’s take an in-depth look at the Gigabyte GV-N65TOC-2GI.

The Gigabyte GV-N65TOC-2GI

Below we have an overall comparison between the Gigabyte GV-N65TOC-2GI and the standard GeForce GTX 650 Ti. Both require one six-pin auxiliary power connector.

Even though the GeForce GTX 650 Ti supports four video monitors, the standard model has only three video connectors, so you are limited to three monitors with the reference model. The Gigabyte GV-N65TOC-2GI, on the other hand, comes with two DVI-D connectors, one HDMI connector, and one VGA connector, supporting four displays.

The standard GeForce GTX 650 Ti uses a 75 mm fan on a small aluminum heatsink. One of the main advantages of the Gigabyte GV-N65TOC-2GI is the use of a better cooling solution, using two 100 mm fans on top of an aluminum heatsink. This custom cooler has two heatpipes that touch the GPU. This cooler, however, doesn’t touch the memory chips. The GeForce GTX 650 Ti has a TDP of 110 W.

The Gigabyte GV-N65TOC-2GI (Contíd)

In Figure 5, you can see the standard GeForce GTX 650 Ti and the Gigabyte GV-N65TOC-2GI with their cooler removed. We were impressed by how short the printed circuit boards are, at 5.7” (145 mm). Even though the printed circuit boards have the same dimensions, Gigabyte took the time to design its own printed circuit board. While the cooler used on the standard model doesn’t add any length to the video card, the cooler used on the Gigabyte’s model makes the card 9.2” (235 mm) long.

Both video cards use a voltage regulator with two phases for the GPU and one phase for the memory chips. The voltage regulator circuit uses a digital design and is controlled by a uP1605 chip. All capacitors are solid. The model from Gigabyte uses better coils than NVIDIA’s reference model. That’s the only difference between the two models on this stage.

The reviewed video card uses eight Hynix H5GQ2H24AFR-ROC GDDR5 chips, each one storing 2 Gbits of data, comprising the 2 GB of memory available on this video card. These chips can run up to 6 GHz. On this video card, they are accessed at 5.4 GHz, leaving you with an 11% margin for safely increasing the memory clock. Since the memory is operating below its maximum clock rate, we see no reason why Gigabyte configured this video card with NVIDIA’s standard clock rate. The reference model uses exactly the same chips, but only four of them, since it only has 1 GB of memory.

Error Margin

We adopted a 3% error margin. Thus, differences below 3% cannot be considered relevant. In other words, products with a performance difference below 3% should be considered as having similar performance.

StarCraft II: Wings of Liberty

StarCraft II: Wings of Liberty is a very popular DirectX 9 game that was released in 2010. Though this game uses an old version of DirectX, the number of textures that can be represented on one screen can push most of the top-end graphics cards to their limits. StarCraft II: Wings of Liberty uses its own physics engine that is bound to the CPU and thus does not benefit from PhysX.

We tested this game at 1920x1080. The “Texture Quality” and the “Graphics Quality” were both set to “Ultra.” We then used FRAPS to collect the frame rate of a replay on the “Unit Testing” custom map. We used a battle between very large armies to stress the video cards

WoW: Mists of Pandaria

World of Warcraft is a very popular MMORPG (Massively Multiplayer Online Role Playing Game) that has just incorporated support for DirectX 11 in its newest expansion, Mists of Pandaria. World of Warcraft was originally released in late 2004 and has been expanded four times since then, with Mists of Pandaria being the newest expansion, released in September 2012. Blizzard, the game’s developer, has been trying to keep the graphics requirements for the World of Warcraft franchise low in order to keep its player base large.

We tested this game at 1920x1080 with image quality set at “high.” To keep as much consistency between tests as possible, we used the same flight path between Sri-La Village and Soggy’s Gamble, which are on opposite sides of the new Mists of Pandaria continent, measuring the performance achieved by each video card using FRAPS

Conclusions

Let’s first talk about the standard GeForce GTX 650 Ti with 1 GB memory. On the games we used in this review, this new video card was between 8% and 39% faster than its main competitor, the Radeon HD 7770, and between 12% and 50% faster than the video card it comes to replace, the GeForce GTX 550 Ti. For transcoding video using Media Espresso, however, the Radeon HD 7770 was 11% faster. Costing only USD 150, we believe the new GeForce GTX 650 Ti is an outstanding video card for the average user.

The Gigabyte GV-N65TOC-2GI, with its overclocking and 2 GB of memory, was up to 12% faster than the standard GeForce GTX 650 Ti. It was between 14% and 52% faster than the Radeon HD 7770 and between 18% and 65% faster than the GeForce GTX 550 Ti on the games we ran.

Speaking only on performance terms, the GV-N65TOC-2GI is not a good buy, since you are going to pay 17% more to get only, in the best-case scenario, 12% more performance. However, if you prefer to have a GeForce GTX 650 Ti with a better cooling solution, the Gigabyte GV-N65TOC-2GI may be an option. We also have to consider that we didn’t do any overclocking to the reviewed video card. We know for a fact that you can increase its memory clock to at least 6 GHz, since it uses memory chips rated at 6 GHz. Also, thanks to its improved cooling, you may be able to increase the GPU clock even more. So, the Gigabyte GV-N65TOC-2GI may be a contender if you are into overclocking video cards.
