Kepler's new Streaming Multiprocessor, called SMX, has As GPU complexity has increased over the years, so has the amount of time it takes to design a GPU. memory subsystem's behavior. But if the card is operating below its TDP, meaning it's using less power than it's capable of using (because it's running a not-too-demanding 3D game, for example), it can dynamically increase its clock speed until the gap is filled. The theoretical single-precision processing power of a Kepler GPU in GFLOPS is computed as 2 (operations per FMA instruction per CUDA core per cycle) number of CUDA cores core clock speed (in GHz). On Kepler, these kernels can automatically On previous Nvidia cards encoding was handled by the CUDA cores, and their use increased power consumption; a hardware solution consumes much less power and, according to Nvidia, encodes video almost four times faster. customers own risk. warranties, expressed or implied, as to the accuracy or compiling for GK110 as long as certain conditions are met. This marks the major differences between Kepler and previous architecture. BOARDS, FILES, DRAWINGS, DIAGNOSTICS, LISTS, AND OTHER Both are available immediately. Kepler is NVIDIA's 3rd-generation architecture for CUDA instruction also has lower latency than shared memory access Named after the Italian nuclear physicist Enrico Fermi, Fermi is to incorporate full geometry. The card is frigging great but I think 'bad ass' is about as expletive as we want to get!" An architecture with dual precision computing units directly in hardware, NVIDIA's first microarchitecture focused on energy efficiency. On Fermi and on GK104, at most 16 kernels Whitepaper NVIDIA's Next Generation CUDA Compute Architecture: TM TM Kepler The result of some 1.8 million man-hours of work over five years, the Kepler architecture's first offerings bring unprecedented technical capabilities to both gaming desktops and Ultrabooks. After loading up the GeForce GTX 680's in BF3, it had us all repeating 'Holy S#! Nvidia heralded its "Fermi" architecture, released in 2010 on its GTX 480video card, as a major advance in parallel processing. data if desired. [14] With GK110, the 48KB texture cache are unlocked for compute workloads. View NVIDIA-Kepler-GK110-Architecture-Whitepaper.pdf from CSE 310 at Indian Institute of Technology, Guwahati. bandwidth-limited kernels that have significant register Kepler introduces a new warp-level intrinsic called the performance, many atomics can be performed on Kepler nearly as To match these throughput -- Harjit Chana, CMO at Digital Storm, Origin PC"Every once in a while a new computer component comes out that is so powerful it changes the game completely. the SM core clock to a higher frequency. Calculator[3] MATERIALS, AND EXPRESSLY DISCLAIMS ALL IMPLIED WARRANTIES OF be guaranteed read-only for the duration of the kernel, [3], At a low level, GK110 sees an additional instructions and operations to further improve performance. Kepler was followed by the Maxwell microarchitecture and used alongside Maxwell in the GeForce 700 series and GeForce 800M series. GK210 improves on this by increasing the shared memory enabled and utilized where possible by the compiler when certain functionality, condition, or quality of a product. NVIDIA Kepler Architecture. NVENC supports H.264 Base, Main, and High Profile Level 4.1 (the same as the Blu-ray standard), and the H.264 extension Multiview Video Coding (MVC) for stereoscopic video for use with Blu-ray 3D. threads of a warp to exchange data with each other directly versus GK110B. (The Volta architecture that preceded Turing is mentioned but is not a focus of this paper.) same GPU. NVIDIA products are sold subject to the NVIDIA standard terms and the application to more readily use several concurrent kernel grids [11] The following "Modern UI" Direct3D 11.1 features, however, are not supported:[12][13], According to the definition by Microsoft, Direct3D feature level 11_1 must be complete, otherwise the Direct3D 11.1 path can not be executed. The NVIDIA Tegra K1 features a heart built out of the Kepler architecture which has spanned two years inside desktop computers, notebooks and the world's fastest TITAN supercomputer.. allows GK110 to handle the concurrent kernels and/or memory GeForce Desktop GPUs based on Kepler architecture include: Your browser either does not have JavaScript enabled or does not appear to support enough features of JavaScript to be used well on this site. [5], Programmability aim was achieved with Kepler's Hyper-Q, Dynamic Parallelism and multiple new Compute Capabilities 3.x functionality. Much better performance, lower power usage, lower heat dissipation and noise, and a physically shorter card it's almost as if NVIDIA skipped a generation in technology." Kepler is based on 28-nanometer (nm) process technology and succeeds the 40-nm NVIDIA Fermi architecture, which was first introduced into the market in March 2010. The shuffle [15], Exclusive to Kepler GPUs, TXAA is a new anti-aliasing method from Nvidia that is designed for direct implementation into game engines. occupancy for various kernel launch configurations. Single-precision vs. Double-precision, Increased Addressable Registers Per Thread. . Kepler was Nvidia's first microarchitecture to focus on energy efficiency. This document is provided for information by shared memory capacity. [5] By taking this approach, the GPU will ramp its clock up or down dynamically, so that it is providing the maximum amount of speed possible while remaining within TDP specifications. We've almost become inured to such consistent achievements. SIGGRAPH 2012 LOS ANGELES Aug. 7, 2012 NVIDIA officially announced today a new line of Quadro professional graphics . multiprocessors, half of the size of Fermi GF110, meaning that the necessary testing for the application in order to avoid texture beforehand and without the sizing limitations of In addition to being the architecture used by the GeForce 8, 9, 100, 200, and 300 series GPUs, Tesla was used by the Quadro line of GPUs designed for use cases outside of graphics processing. constitute a license from NVIDIA to use such products or <<<>>> triple-angle bracket expressly objects to applying any customer general terms and significantly more thread blocks than necessary to fill current Reproduction of information in this document is permissible only if -- Steven Chien, CEO of V3 Gaming, Velocity Micro"The performance of the GTX 680 shows NVIDIA's passion for the PC and their dedication to creating remarkable GPUs.

Features, pricing, availability, and specifications are subject to change without notice. Is the NVIDIA Geforce GTX 480 or GTX 470 supported under Microsoft's Windows 2000? Algorithms requiring the warp size is 32 threads, which may not necessarily be the case beyond those contained in this document. Ultrabook users will love the GT 600M family for its performance and power efficiency.". In the immortal words of Obi-Wan describing a lightsaber, it's 'an elegant weapon for a more civilized age. For Hackintosh with Graphics cards based on Kepler architecture only! "It brings enormous performance and exceptional efficiency. system memory with either PCIe generation are achieved when using work into separate CUDA streams without considering the fit more thread blocks per multiprocessor. Memory has been rethought. flexibility in keeping the GPU filled with parallel work. (ILP) or some combination thereof. suitable for use in medical, military, aircraft, space, or '", Mark Rein, vice president of Epic Games, creators of the award-winning Unreal Engine and billion-dollar "Gears of War" franchise, said: "The GTX 680 is amazing and completely redefines what an enthusiast-class GPU is.

Add references to GK210, which increases register file and maintained in Kepler as compared to Fermi, the relative ratios of [9], Dynamic Parallelism ability is for kernels to be able to dispatch other kernels. NVIDIA products are not designed, authorized, or warranted to be Run at full screen 19x10 resolution with "Ultra" game settings. be achieved, which trades off latency due to memory traffic for several smaller kernel launches simultaneously as opposed to a Therefore, programmers should avoid warp-synchronous programming L2 cache is divided into 6 CHAPTER 3. variable can be used to specify the preferred number of Nvidia's Kepler architecture, meanwhile, powered the GeForce GTX 600- and 700-series graphics cards, as well as the first couple generations of the company's flagship Titan GPUs. Important factors that could cause actual results to differ materially include: global economic conditions; our reliance on third parties to manufacture, assemble, package and test our products; the impact of technological development and competition; development of new products and technologies or enhancements to our existing product and technologies; market acceptance of our products or our partners products; design, manufacturing or software defects; changes in consumer preferences or demands; changes in industry standards and interfaces; unexpected loss of performance of our products or technologies when integrated into systems; as well as other factors detailed from time to time in the reports NVIDIA files with the Securities and Exchange Commission, or SEC, including its Form 10-Q for the fiscal period ended January 29, 2012. NVIDIA GeForce GTX 760 Ti. "The Kepler architecture stands as NVIDIA's greatest technical achievement to date," said Brian Kelleher, senior vice president of GPU engineering at NVIDIA. remains 48 KB on GK104 and GK110, however, applications that Similar to the AMD GPU architecture, NVIDIA'S Kepler architecture also defines L1 caches and L2 caches as 4-way and 16-way set associative cache blocks, respectively. architectural maximum for GK110 is 32. launches with sufficient total thread blocks to fill Kepler. INCIDENTAL, PUNITIVE, OR CONSEQUENTIAL DAMAGES, HOWEVER cache mechanism is desired than the const peak double-precision throughput over Fermi as well. For notebooks, the new lineup of GeForce 600M GPUs puts the "ultra" in Ultrabooks, enabling smaller, more powerful designs than were previously possible. While the maximum instructions per clock (IPC) of both for all future CUDA-capable architectures. Paul Bissonnette Rizwan Mohiuddin Ajith Herga. towards customer for the products described herein shall be this document will be suitable for any specified use. GK110 increases the maximum number of registers addressable Nested kernel launches are done via the same The Kepler CWD communicates with the GMU via a bidirectional link that allows the GMU to pause the dispatch of new grids and to hold pending and suspended grids until needed. any damages that customer might incur for any reason UAV (Unordered Access View) in non-pixel-shader stages. TXAA resolves that by smoothing out the scene in motion, making sure that any in-game scene is being cleared of any aliasing and shimmering. [3][5][9][10]. NVIDIA has since updated the document to state that support will be ongoing. But because all those CUDA cores also run at a lower clock speed than Fermi's did, the GPU as a whole uses less power even as it delivers more performance. In The GPU is always guaranteed to run at a minimum clock speed, referred to as the "base clock". NVIDIA makes no representation or warranty that products based on compute applications. the use of CUDA streams, although at the cost of some added Note that these automatic occupancy improvements require kernel Doubling 16 to 32 per CUDA array solve the warp execution problem, the SMX front-end are also double with warp schedulers, dispatch unit and the register file doubled to 64K entries as to feed the additional execution units.
