Intel's second generation of 32-bit x86 processors, introduced built-in floating point unit (FPU), 8 KB on-chip L1 cache, and pipelining. Faster per MHz than the 386. Small number of new instructions. P5 original Pentium microprocessors, first x86 processor with super-scalar architecture and branch prediction. P6
Some Xeon Phi processors support four-way hyper-threading, effectively quadrupling the number of threads. [1] Before the Coffee Lake architecture, most Xeon and all desktop and mobile Core i3 and i7 supported hyper-threading while only dual-core mobile i5's supported it.
Multithreading, multi-core, 8 fine-grained threads per core of which 2 can be executed simultaneously, 2-way simultaneous multithreading, 6 cores per chip, out-of-order, 48 MB L3 cache, out-of order execution, RAS features, stream-processing unit, hardware-assisted cryptographic acceleration, 6 cryptography units per chip, Hardware random ...
Benchmarks are particularly important in CPU design, giving processor architects the ability to measure and make tradeoffs in microarchitectural decisions. For example, if a benchmark extracts the key algorithms of an application, it will contain the performance-sensitive aspects of that application. Running this much smaller snippet on a cycle ...
Raptor Cove, released on October 20, 2022 with Raptor Lake processors, is a refresh of the Golden Cove microarchitecture with the following changes: Boost frequency up to 6.2 GHz 2 MB L2 cache , [ 19 ] up from 1.25 MB on the mainstream desktop variant of Golden Cove.
The roofline model is an intuitive visual performance model used to provide performance estimates of a given compute kernel or application running on multi-core, many-core, or accelerator processor architectures, by showing inherent hardware limitations, and potential benefit and priority of optimizations.
According to AMD, Bulldozer-based CPUs are based on GlobalFoundries' 32 nm Silicon on insulator (SOI) process technology and reuses the approach of DEC for multitasking computer performance with the arguments that it, according to press notes, "balances dedicated and shared computer resources to provide a highly compact, high units count design that is easily replicated on a chip for ...
AMD has not used K-nomenclature codenames in official AMD documents and press releases since the beginning of 2005, when K8 described the Athlon 64 processor family. AMD now refers to the codename K8 processors as the Family 0Fh processors. 10h and 0Fh refer to the main result of the CPUID x86 processor instruction.
