It is built on the same Keplar architecture as the GeForce 600 GPUs. The 700 series firstly appeared with the 2688-CUDA core GTX Titan February in the year 2013, followed by the GTX 770 and GTX 780 a few months later and then the single-GPU flagship GTX 780 Ti in November. Although the GTX 770 was indispensable a rebadged GTX 680 with faster memory, the GTX 780 and GTX 780 Ti were all new products, even if they featured the same design. Overall, the GeForce 700 series pushed Kepler to its limits-all with the exception of the GTX 750 Ti.

It is being priced at $150. The GTX 750 Ti was similar to the GTX 650 Ti Boost in terms of frame rate performance in spite of its appearing alike it should have been 20% slower on paper. It has made up in efficiency with the next-gen Maxwell design, which the GTX 750 Ti already lacked. The GTX 650 Ti packs 20% more cores, 60% more TAUs and 50% more ROPs whereas the GTX 750 Ti has a sheer 5% core clock speed advantage, yet it can match and at times it can beat the GTX 650 Ti while using 20% less power. With such a strong bringing, Maxwell’s debut had excited the users for higher-end cards and today they finally have it. The GTX 970 Ti costing $329 will try to carve a place out for itself between the R9 280X and R9 290, whereas the GTX 980 that costs $549 is positioned against the R9 290X.

Gigabyte G1 Gaming GTX 970 and GTX 980: When starting with the more expensive GTX 980, all the gamers might be astonished to find out that though this card is priced to match the GTX 780 Ti, but on paper, it doesn’t stand a chance to do anything. The GTX 780 Ti boast 15 SMX units for a core count of 2880, with 240 TAUs and 48 ROPs as well as GDDR5 memory clocked at 1753 MHz (7.0Gbps) and a 384-bit wide memory bus that is ready to offer a bandwidth of 336.4GB/s. When compared, the GTX 980 seems to be underwhelming with just 2048 cores, 128 TAUs and 64 ROPs. That’s 29% less cores, 47% less TAUs and 33% less ROPs. The GTX 980 is also limited to a 256-bit memory bus, and with the GDDR5 memory still clocked at 1753 MHz (7.0Gbps) this allows for a memory bandwidth of just 224GB/s, or 33% less than the GT^X 780 Ti.

New Maxwell Features: The Company has mentioned that the new Maxwell is bringing about 2x the performance per watt over the previous generations. For instance, the GTX 980 has 33% more cores that also operate at a higher frequency than the GTX 680, yet the newer card’s TDP rating is calculated at 30 watts which is low. Finally, the GTX 980 and the GTX 970’s connectivity have also been improved. The I/O bracket provides three standard Display Port connectors and a HDMI 2.0 connector that supports 4K resolutions at 60Hz.
