Gaming Performance Comparison

In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R9 270X are significantly better than the Nvidia GeForce GTX 750 Ti.

The GTX 750 Ti has a 20 MHz higher core clock speed than the Radeon R9 270X, but the Radeon R9 270X has 40 more Texture Mapping Units than the GTX 750 Ti. As a result, the Radeon R9 270X exhibits a 39.2 GTexel/s better Texture Fill Rate than the GTX 750 Ti. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GTX 750 Ti has a 20 MHz higher core clock speed than the Radeon R9 270X, but the Radeon R9 270X has 16 more Render Output Units than the GTX 750 Ti. As a result, the Radeon R9 270X exhibits a 15.7 GPixel/s better Pixel Fill Rate than the GTX 750 Ti. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GTX 750 Ti was released less than a year after the Radeon R9 270X, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The Radeon R9 270X and the GeForce GTX 750 Ti have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The Radeon R9 270X has 92.8 GB/sec greater memory bandwidth than the GTX 750 Ti, which means that the memory performance of the Radeon R9 270X is massively better than the GTX 750 Ti.

The Radeon R9 270X has 1280 Shader Processing Units and the GeForce GTX 750 Ti has 640. However, the actual shader performance of the Radeon R9 270X is 1210 and the actual shader performance of the GTX 750 Ti is 937. The Radeon R9 270X having 273 better shader performance and an altogether better performance when taking into account other relevant data means that the Radeon R9 270X delivers a massively smoother and more efficient experience when processing graphical data than the GTX 750 Ti.

The Radeon R9 270X requires 180 Watts to run and the GeForce GTX 750 Ti requires 60 Watts. We would recommend a PSU with at least 500 Watts for the Radeon R9 270X and a PSU with at least 300 Watts for the GTX 750 Ti. The Radeon R9 270X requires 120 Watts more than the GTX 750 Ti to run. The difference is significant enough that the Radeon R9 270X may have an adverse affect on your yearly electricity bills in comparison to the GTX 750 Ti.

GPU Mini Review

Mini ReviewRadeon R9 270X is a high-end Graphics Card based on the Curacao XT core of the Graphics Core Next Architecture.
The Curacao XT Core has its roots on the Pitcairn XT Core used on its predecessor - Radeon HD 7870. It offers 1280 Shader Processing Units, 80 TMUs and 32 ROPs, on a 256-bit memory interface.
However and when compared to its predecessor, Radeon R9 270X offers a Boost Clock of 1050MHz, despite its central unit still running at 1000MHz. Furthermore, its operating memory clock is significantly higher and of 1400MHz, leading to extra memory bandwidth.
Benchmarks indicate its performance is almost on level with powerful Radeon HD 7950, though its Boost Edition and famous GeForce GTX 660 Ti still perform considerably better.
Still, Radeon R9 270X has a launching price of just $199 which makes it a very competitive card.
Expect to run most modern demanding games, such as Crysis 3 and Metro Last Light at highest settings while using a 1080p resolution.
Overview
GeForce GTX 750 Ti is a performance Graphics Card based on the first variant of the Maxwell architecture.

Architecture
The first variant of the Maxwell Architecture succeeds the Kepler Architecture. Despite being also manufactured with a 28nm technology, it has an extremely large L2 Cache which allows NVIDIA to produce Graphics Cards with relatively small memory data transfer rates, without causing too much impact on the overall performance. Furthermore, the Shaders have been redesigned and are both more powerful and energy efficient.

GPU
It equips a GPU codenamed GM107-400-A2 which has 5 SM activated and thus offers 640 Shader Processing Units, 40 TMUs and 16 ROPs, on a 128-bit memory interface of fast GDDR5. The central unit runs at 1020MHz and goes up to 1085MHz, in Turbo Mode, while the memory clock operates at 1350MHz.

Features
DirectX 11.2 Support (11.0 Hardware Default) and support for GameStream, G-SYNC, GPU Boost 2.0, GeForce Experience, PhysX and other technologies.

Cooling Solution
The Cooling Solution consists of a Single-Fan and is identical to the one seen on GeForce GTX 650. The Card is known to run very cool and has a maximum operating temperature of 95ÂșC.

Power Consumption
With a rated board TDP of 60W, it requires at least a 300W PSU and relies entirely on the PCI Slot for power.

Release Price
Pricing is identical to the one seen on its predecessors - $149.

Performance
Benchmarks indicate its performance is largely better than its predecessor's but Radeon HD 7850 and GeForce GTX 650 Ti Boost Edition still offer better performance, due to their high memory bandwidth transfer rates.

System Suggestions
We recommend a strong processor (Intel Core i5 Quad Core/AMD FX Six Core) and 8GB of RAM for a system with GeForce GTX 750 Ti.
