NVIDIA GeForce GTX 650 Ti
Date issued:
NVIDIA is today releasing the GeForce GTX 650 Ti graphics card. It is designed to offer a solid gaming experience at a full-HD, 1,920x1,080 resolution that is common on most LCD monitors.
Priced from £120 and with a number of models available right now from Scan.co.uk, GeForce GTX 650 Ti uses NVIDIA's established Kepler graphics processing unit (GPU) technology to provide mid-range excellence for both gaming and multimedia usage.
Understanding how the GTX 650 Ti works requires a comparison between it and the last-generation card it replaces, GeForce GTX 550 Ti, and the card immediately above it in the GeForce pecking order, GTX 660. The following table provides an in-depth look at the relative speeds and feeds.
| GPU | GeForce GTX 660 (2,048MB) |
GeForce GTX 650 Ti (1,024MB) |
GeForce GTX 550 Ti (1,024MB) |
|---|---|---|---|
| Die codename | Kepler GK106 | Kepler GK106 | Fermi GF116 |
| DX API | 11.1 | 11.1 | 11 |
| Process | 28nm | 28nm | 40nm |
| Transistors | 2.54bn | 2.54bn | 1.17bn |
| Die Size | 221mm² | 221mm² | 238mm² |
| SMX units | 5 | 4 | 4 |
| Processors | 960 | 768 | 192 |
| Texture Units | 80 | 64 | 32 |
| ROP Units | 24 | 16 | 24 |
| GPU Clock (MHz) | 980 | 925 | 900 |
| Shader Clock (MHz) | 980 | 925 | 1,800 | Boost Clock (MHz) | 1,033 | NA | NA |
| GFLOPS | 1,882 | 1,421 | 691 |
| Memory Clock (MHz) | 6,008 | 5,400 | 4,100 |
| Memory Bus (bits) | 192 | 128 | 192 |
| Max bandwidth (GB/s) | 144.2 | 86.4 | 98.5 |
| Power Connectors | 6-pin | 6-pin | 6-pin |
| TDP (watts) | 140 | 105 | 115 |
| GFLOPS per watt | 13.44 | 13.53 | 6.01 |
| Current MSRP | £170 | £120 | £90 |
Shown in the middle, GTX 650 Ti clearly uses the same underlying Kepler technology as found on the £170-plus GeForce GTX 660. NVIDIA reduces the number of GPU processors, ROPs, memory interface and speed - the building blocks of a GPU - in order to construct the GTX 650 Ti. What's more, the newest card also does without the 'GPU Boost' ability of its bigger brother, where the GPU automatically overclocks to a higher frequency if there is headroom to do so.
But the real comparison is between NVIDIA's x50 Ti generations, and 650 Ti is better than 550 Ti in all performance parameters other than memory bandwidth. The end result is a card that, according to leading review websites, is around 50 per cent faster than the last-gen GTX 550 Ti. Not only that, it is more power-efficient, too, thanks to the advanced, industry-leading 28nm manufacturing process used on Kepler-grade GPUs.
Putting the performance into context, GTX 650 Ti is able to run the very latest games at high-quality settings at the full-HD, 1,920x1,080-pixel resolution that most gamers care about.
The above picture illustrates a reference GeForce GTX 650 Ti graphics card. It measures just 5.65in long and is therefore suitable for inclusion in a wide range of chassis, including small-form-factor cases. Note, however, that the cooler is roughly 1.5x the height of the backplate. This means that users may not be able to house another expansion card next to it. Not shown on the above picture, the card requires a six-pin PCIe connector from the PSU in order to run properly.
While the size is small and the heatsink-and-fan unit enable low temperatures and quiet operation, NVIDIA's default video outputs of two dual-link DVI and mini-HDMI enable the card to be connected to three monitors at one time. NVIDIA's multi-monitor know-how allows the GeForce GTX 650 Ti to render a game on to the three screens under the firm's software-based Surround technology - ultra-widescreen gaming, if you will.
Summarising it succinctly, GeForce GTX 650 Ti makes a lot of sense if you're looking for a mid-priced graphics card that is full of features and is able to play the latest games at the full-HD resolution together with console-beating image-quality settings. It uses NVIDIA's proven, tried-and-trusted Kepler gaming architecture to good effect, thereby comfortably beating out the last-generation GeForce GTX 550 Ti in all gaming tests.
NVIDIA's add-in card partners are sure to release a broad range of GeForce GTX 650 Ti boards in the coming days and weeks. You can be sure that Scan Computers will stock the widest selection of boards in the UK.
