The Intel Core i7-6700K is a high-end quad-core desktop processor based on the Skylake architecture, which was announced in August 2015. The CPU, which is manufactured in a 14 nm process, runs at 4.0 up to 4.2 GHz (2 cores: 4.0 GHz, 3 cores: 4.0 GHz, 4 cores: 4.0 GHz) and can execute up to 8 threads simultaneously thanks to Hyperthreading. Being a so called "K"-model, the Core i7-6700K has a free multiplier and can be easily overclocked.
Performance
Even though the Core i7-6700K has a slightly lower clock than the old i7-4790K (4.0 GHz - 4.4 GHz), the performance is slightly better compared to the Haswell predecessor. Depending on the application, the per-MHz performance was increased by roughly 5-10 %. Even the most demanding applications and games are no problem for the high-end CPU.
Graphics
Graphics are handled by the integrated Intel HD Graphics 530 with 24 EUs (Execution Units), which is clocked at 350 - 1150 MHz. Compared to the HD Graphics 4600 (Haswell, 20 EUs), the performance is increased by around 25 percent. The overall GPU performance is still low-end, so modern games can, if at all, only be played smoothly with low settings.
Power Consumption
The TDP was slightly raised from 88 to 91 Watts compared to the predecessor.
The Intel Core i3-N305 is an entry-level mobile CPU for thin and light laptops from the Alder Lake-N series. It was announced in early 2023 and offers no performance cores and 8 efficient cores (E-cores, Gracemont architecture). The chip does not support HyperThreading and clocks with up to 3.8 GHz (single core, 3 GHz all core Turbo). The performance of the E-cores should be similar to old Skylake cores (compare to the Core i7-6700HQ). All cores can use up to 6 MB L3-cache.
Performance
The performance depends on the cooling and TDP settings and should be somewhere similar to the old Alder Lake Pentium 8500 (1 performance core, 4 efficiency cores, max. 4.4 GHz and 8 MB L3-cache). The multi-threaded performance should be quite good with the 8 cores but will suffer due to the low TDP. Single thread performance will suffer due to the missing P-cores and relatively low boost clock speeds.
Features
The Alder Lake-N chips only support single channel memory with up to DDR5-4800, DDR4-3200 or LPDDR5-4800. The chip also supports Quick Sync and AV1 decoding (most likely same engine as in Alder Lake). Furthermore, Wi-Fi 6E and Bluetooth 5.2 are partly integrated (but no Thunderbolt). External chips can be connected via PCIe Gen3 x9 (via the PCH).
The integrated graphics adapter is based on the Xe-architecture and offersall 32 EUs (Execution Units) operating at up to 1.25 GHz. In addition to the single channel memory, the gaming performance is very limited of the iGPU.
Power consumption
The i3 has a base power consumption of 7 W and is therefore even suited for fanless cooling. The CPU is built with a further improved 10nm SuperFin process at Intel (called Intel 7).
The Intel Core i7-6700 is a high-end quad-core desktop processor based on the Skylake architecture, which was announced in August 2015. The CPU, which is manufactured in a 14 nm process, runs at 3.4 up to 4.0 GHz (2 cores: 3.9 GHz, 4 cores: 3.7 GHz) and can execute up to 8 threads simultaneously thanks to Hyperthreading. Contrary to the Core i7-6700K, the i7-6700 does not have a free multiplier and can hardly be overclocked.
Architecture
Intel uses Skylake to replace both Broadwell and Haswell and therefore once again uses one core design for all TDP classes. Several improvements of the Skylake architecture include bigger Out-to-Order-Buffer, optimizations for pre-fetching as well as bigger gains by Hyperthreading. However, the changes are small for a "Tock" – a new micro architecture – in general, so the per-MHz performance is only between 5-10 % (compared to Haswell) or less than 5 % higher (compared to Broadwell), respectively.
Performance
Even though the Core i7-6700 has a slightly lower clock than the old i7-4790 (3.6 GHz - 4.0 GHz), the performance is slightly better compared to the Haswell predecessor. Another 7 % faster is the top model i7-6700K. Even the most demanding applications and games are no problem for the high-end CPU.
Graphics
Graphics are handled by the integrated Intel HD Graphics 530 with 24 EUs (Execution Units), which is clocked at 350 - 1150 MHz. Compared to the HD Graphics 4600 (Haswell, 20 EUs), the performance is increased by around 25 percent. The overall GPU performance is still low-end, so modern games can, if at all, only be played smoothly with low settings.
