NVIDIA have just released it’s new first generation Maxwell based graphics card, the GeForce GTX 750 Ti, and here is our review.
The GeForce GTX 750 Ti is designed to deliver the horsepower necessary to drive today’s most demanding titles in full 1080p HD. It delivers 25% more performance than previous generation cards and up to twice the power efficiency thanks to the new Maxwell architecture.
Maxwell
This is what NVIDIA says about Maxwell:
Efficiency is all about doing more with less. The way we achieved better efficiency in Maxwell is by increasing the utilization of our cores. This increases computation.
With Kepler, the SM contained control logic that routed and scheduled traffic for 192 cores. This was complex for a single piece of control logic. With Maxwell, we divided the SM into four blocks, each with its own piece of control logic. The control logic now manages 32 cores instead of 192, making its task much simpler.
By breaking up one giant problem of the control logic doing the scheduling and threading on each SM into smaller work, and by performing the global partitioning in software, we were able to design the chip to be more efficient. As a result, we’ve actually increased the amount of peak performance per core by 35% when compared to the cores in chips built with the previous generation Kepler architecture.
Since we are using less overall cores to get more performance, less power is ultimately used, increasing the performance/watt for the Maxwell architecture. A number of additional optimizations were made inside the chip to increase power efficiency.
The GeForce GTX 750 Ti
The GeForce GTX 750 Ti is designed for gamers who want to enjoy their games at 1080p with normal to high settings without breaking the bank. At the heart of the GeForce GTX 750 Ti lies our first-generation Maxwell GM107 GPU with 640 CUDA Cores. The memory subsystem of GeForce GTX 750 Ti consists of two 64-bit memory controllers (128-bit) with 1GB or 2GB of 5.4Gbps GDDR5 memory.
GeForce GTX 750 Ti also ships with GPU Boost 2.0 technology, ensuring that the graphics card is always running at the highest clocks possible for the very best gaming performance under varied operating conditions. With Boost 2.0, NVIDIA also guarantee a minimum level of performance no matter the workload or thermal/power conditions.
The base clock speed of the GeForce GTX 750 Ti is 1020MHz. The typical Boost Clock speed is 1085MHz. The Boost Clock speed is based on the average GeForce GTX 750 Ti card running a wide variety of games and applications. Note that the actual Boost clock will vary from game-to-game depending on actual system conditions.

A Closer Look
As you can see, the size of the card is significantly smaller than that of the GTX 680, both in length and width.
