On Tuesday, Nvidia’s GPU product roadmap was announced and, in addition, Intel exposed the features of the expected “Haswell” microarchitecture, offering the computing industry observers the opportunity to take a brief look at the future.
Regarding the 2016 release that Nvidia is planning, the chief executive officer, Jen-Hsun Huang held a speech at the GPU Technology Conference in San Jose, asserting that Volta is expected to solve one of the biggest problems of GPUs, the access to memory bandwidth, being able to leverage stacked DRAM technology to deliver 1 terabyte per second of memory bandwidth as Forbes emphasized.
Volta will reach these speeds by stacking DRAM on top of the GPU, with a silica substrate separating them. Drilling through the silicon, Nvidia is able to connect the two layers, and, as a result, the GPU will be capable of moving the equivalent of a full Blu-Ray disc in 1/50th of a second.
The Haswell Architecture is Expected to Show Up in iMacs
Regarding the Haswell architecture, it is known that, in accordance with a document that appeared last year, it is anticipated to be available with iMacs later in 2013. On the high end, the Core i7-4770K processor will run at a base frequency of 3.5GHz, with 8MB of memory. With Intel Turbo Boost Technology, it will max out at 3.9 gigahertz.
Recently, Tom’s Hardware obtained a sample of the Haswell chip and put the silicon through its paces. It is not final silicon, but it appeared that the Haswell possesses significant improvements.
In regards to what will be included in the 2013 Haswell lineup, it can be said that there will be a total of six “standard power” desktop processors and that two of them will be more powerful Core i7 models. In addition, there will be eight “low power” processors which include three Core i7 variations.
The slowest processor of the bunch is the Core i5-4430S, which will run at 2.7 gigahertz base frequency with 6 megabytes of total cache, 4 cores and 4 threads.
The most powerful among the low power processors is the Core i7-4770S, which will have a base frequency of 3.1 gigahertz, but can run at up to 3.9 gigahertz with Turbo Boost.
The listed Haswell desktop processors are most expected to make their way into Apple’s all-in-one iMac lineup. These are the only Macs to use desktop processors. The Mac Pro uses Intel’s Xeon server chips while the Mac mini currently relies on low-power mobile processors.
