Instructions per second (IPS) is a measure of a computer's processor speed. For complex instruction set computers (CISCs), different instructions take different amounts of time, so the value measured depends on the instruction mix; even for comparing processors in the same family the IPS measurement can be problematic.
Core i7, on the desktop platform no longer supports hyper-threading; instead, now higher-performing core i9s will support hyper-threading on both mobile and desktop platforms. Before 2007 and post-Kaby Lake, some Intel Pentium and Intel Atom (e.g. N270, N450) processors support hyper-threading. Celeron processors never supported it.
Intel Haswell Core i7-4771 CPU, sitting atop its original packaging that contains an OEM fan-cooled heatsink. This generational list of Intel processors attempts to present all of Intel's processors from the 4-bit 4004 (1971) to the present high-end offerings. Concise technical data is given for each product.
List of AMD Phenom processors. Athlon II (2009) Turion II ( Caspian) More info (2009) K10 series APUs (2011–2012) Concrete products are codenamed "Llano": List of AMD accelerated processing units . Llano AMD Fusion ( K10 cores + Redwood -class GPU) (launch Q2 2011, this is the first AMD APU) uses Socket FM1.
The first processor released with the Nehalem architecture is the high-end desktop Core i7, which was released in November 2008. This is the server version for single CPU systems. This is a single-socket Intel Xeon processor designed for uniprocessor workstations. The performance improvements over the previous Xeon 3300 series are based mainly on:
The Zilog Z80 is an 8-bit microprocessor designed by Zilog that played an important role in the evolution of early computing. Software-compatible with the Intel 8080, it offered a compelling alternative due to its better integration and increased performance. The Z80 boasted fourteen registers compared to the 8080's seven, along with additional ...
All the CPUs support dual-channel DDR4 RAM at up to 2400 MT/s speed. Models i5 and up support it at up to 2666 MT/s speed. All CPU models provide 16 lanes of PCIe 3.0. All CPUs feature a DMI 3.0 bus to the chipset . L1 cache: 64 KB (32 KB data + 32 KB instructions) per core. L2 cache: 256 KB per core. Fabrication process: 14 nm.
Clock rate. Microprocessor clock speed measures the number of pulses per second generated by an oscillator that sets the tempo for the processor. It is measured in hertz (pulses per second). In computing, the clock rate or clock speed typically refers to the frequency at which the clock generator of a processor can generate pulses, which are ...
