Grosch's law is the following observation of computer performance, made by Herb Grosch in 1953: [1]. I believe that there is a fundamental rule, which I modestly call Grosch's law, giving added economy only as the square root of the increase in speed — that is, to do a calculation ten times as cheaply you must do it hundred times as fast.
Sixteen Neurocore chips simulate one million neurons and billions of synaptic connections, claimed to be 9000 times faster as well as more energy efficient than a typical PC. [95] In 2015, Intel and Micron announced 3D XPoint, a non-volatile memory claimed to be significantly faster with similar density compared to NAND. Production scheduled to ...
In contrast, one may need to perform less work to make part A perform twice as fast. This will make the computation much faster than by optimizing part B, even though part B's speedup is greater in terms of the ratio, (5 times versus 2 times). For example, with a serial program in two parts A and B for which T A = 3 s and T B = 1 s,
In 1970 Data General Corporation released the Nova 1200, a minicomputer twice as fast as previous models. Upon purchaser's request, Data General Corporation would include with the computer design documentation intended to allow customers to maintain and repair their own computers.
For example, an IBM PC with an Intel 80486 CPU running at 50 MHz will be about twice as fast (internally only) as one with the same CPU and memory running at 25 MHz, while the same will not be true for MIPS R4000 running at the same clock rate as the two are different processors that implement different architectures and microarchitectures ...
Computer systems make use of caches—small and fast memories located close to the processor which store temporary copies of memory values (nearby in both the physical and logical sense). Parallel computer systems have difficulties with caches that may store the same value in more than one location, with the possibility of incorrect program ...
The K computer is a water-cooled, homogeneous processor, distributed memory system with a cluster architecture. [32] [49] It uses more than 80,000 SPARC64 VIIIfx processors, each with eight cores, for a total of over 700,000 cores—almost twice as many as any other system. It comprises more than 800 cabinets, each with 96 computing nodes (each ...
As seen from the table, the ABC 800 was approximately twice as fast as the IBM PC on floating point calculations, except for BM8 where it was only 20% faster. Using integer variables (only measured for the older ABC 80 in this test) the numbers would be approximately 2-3 times as low (i.e. speeds 2-3 times as high) as for the single precision ...
