Nvidia formally announces high-end GeForce GTX 700M models
Despite increasing competition from increasingly powerful onboard GPUs, Nvidia continues to build luxury discrete solutions that are much more powerful than what any integrated solution can currently offer. The graphics developer currently holds a significant market share with regards to discrete graphics at around 70 percent worldwide. This advantage over AMD is not expected to shrink as the high-end GeForce 700M models will be complementing the launch of Intel's Haswell generation of CPUs.
Though it is a new generation above the GeForce 600M series, the high-performance 700M models will be based on the already established Kepler architecture manufactured under a 28 nm process at TSMC. Nvidia promises significant performance improvements due to higher base clock rates and additional Shader units.
|Graphics Card||GeForce GTX 760M||GeForce GTX 765M||GeForce GTX 770M||GeForce GTX 780M|
|Core clock||up to 657 MHz + Boost||up to 850 MHz + Boost||up to 811 MHz + Boost||up to 823 MHz + Boost|
|Memory clock||2000 MHz||2000 MHz||2000 MHz||2500 MHz|
|Memory interface||128 Bit||128 Bit||192 Bit||256 Bit|
|Memory configuration||up to 2 GB GDDR5||up to 2 GB GDDR5||up to 3 GB GDDR5||up to 4 GB GDDR5|
The top model in the lineup is the GTX 780M designed for large and heavier DTRs. Its 1536 Shader cores (compared to 1344 in the GTX 680M) and up to 823 MHz core clock with Boost surpasses the processing power of the GTX 680M by a 30 percent margin. Memory clock has also been raised from 1800 MHz to 2500 MHz compared to the previous generation, resulting in a memory bandwidth of 160 GB/s. Overall improvements are expected to provide a performance increase of over 30 percent in games. Power requirements will be on par with AMD's high-end Radeon HD 8970M, whose performance is similar to the new Nvidia equivalent, at least when judging from initial benchmarks.
Directly below the GTX 780M is the GTX 770M, which replaces the older GTX 670MX. While the number of Shader units (960 cores) have remained intact, core clock speeds have increased noticeably compared to the GK106 core. At up to 811 MHz with Boost and a 2000 MHz memory clock on a 192-Bit interface, users can expect around a 40 percent increase in performance compared to the GTX 675MX.
Finally, the two smaller models are the GTX 760M and GTX 765M, both of which are based on a slightly modified GK106 core. 768 Shader units are enabled for both models, albeit core clocks will differ: 657 MHz and 850 MHz for the 760M and 765M, respectively. Otherwise, both models share the same 128-bit memory interface, 2000 MHz memory clock and GDDR5 RAM. Its raw specifications place the 765M and 760M directly below the 675M and 670MX, respectively.
Beyond some high-end barebones providers like Schenker or Eurocom, the first manufacturers to include Nvidia's high-end cards will be Asus, Acer and MSI. Not much is known about these upcoming models, but they will definitely be sporting Intel Haswell processors as well. Wide availability is expected very shortly as more details emerge.
