One of our key items to watch in this segment from the initial announcement is that i3-8100. Another interesting point is the cache: the i3-8350K has 2 MB of 元 cache per core, whereas the i3-8100 only has 1.5 MB of 元 cache per core. Nonetheless, the Core i3s do retain the policy of no Turbo modes on these parts. With the Core i3-K now being quad-core, and overclocking it to try and beat a six-core chip for less money, for certain things like gaming we might see less of a difference between the two. This is a little bit of a surprise: in our testing of the previous generation overclockable Core i3, the fact that it was dual core was a setback in a lot of testing. However at the bottom of the stack are the 4C/4T Core i3 processors, where Intel is pushing out an overclockable Core i3 processor again. This is likely because a 4C/8T processor might overtake a 6C/6T part in some multi-threaded tests (it would also explain why moving from a previous 4C/8T Core i7 processor to a 6C/6T Core i5 8 th generation is not always an increase in performance). With the move to 6C/12T on the high-end Core i7, and 6C/6T on the mid-range Core i5, Intel completely skips the 4C/8T parts and moves straight to 4C/4T on the Core i3. This layout had staggered, regular steps. It is interesting to note that in the last generation, Intel had processors with two cores and two threads (2C/2T), two cores with hyperthreading (2C/4T), quad cores with four threads (4C/4T) and quad cores with hyperthreading (4C/8T).
Comparing cache sizes to the Core i7, the new parts have the same L2 configuration at 256 KB per core, but have a reduced 元 at 1.5 MB per core as part of the product segmentation. Intel sampled us the Core i5-8400 for our review, because it hits an important metric: six cores for under $200. The two Core i5 parts operate at lower clockspeeds compared to the Core i7, and perhaps more so than we are previously used to, especially with the Core i5-8400 having a base frequency of 2.8 GHz. In the middle of the stack are the Core i5 processors, with the new generation matching the ‘same configuration without hyperthreading’ philosophy that followed in the previous generation. In almost all situations this counts as a win-win, and makes pushing for the 6-core part, on paper at least, a no-brainer. However, in order to keep the responsiveness higher than the previous generation, the single thread performance is often pushed to a higher multiplier. The Core i7-8700K is a good example of how adding cores works: in order to keep the same power consumption, the overall base frequency has to be lowered to match the presence of extra cores. When compared to the previous generation, the Core i7-8700K starts at a higher price, but for that price comes more cores and a higher turbo frequency. Both of these processors use 256 KB of L2 cache per core and 2 MB of 元 cache per core. The Core i7-8700 is the non-K variant, with lower clocks (3.2 GHz base, 4.6 GHz turbo) and a lower TDP (65W). The K designation means this processor is unlocked and can be overclocked by adjusting the frequency multiplier, subject to appropriate cooling, applied voltage, and the quality of the chip (Intel only guarantees 4.7 GHz). The Core i7-8700K starts at a 3.7 GHz base frequency and is designed to turbo to 4.7 GHz in single threaded workloads, with a thermal design power (TDP) of 95W. In previous generations ‘Core i7’ meant that we were discussing quad-core parts with hyperthreading, but for this generation it moves up to a six-core part with hyperthreading.
Intel 8th Generation 'Coffee Lake' Desktop ProcessorsĪt the top of the stack are two Core i7 Coffee Lake processors. However due to differences in the pin-layout of these two sets of processors, 8 th Gen will only work in Z370 boards and there is no level of cross compatibility. Technically these processors use the LGA1151 socket, which is also used by the 6 th Generation and 7 th Generation processors with the Z170 and Z270 chipsets. To start, the processor stack that Intel is making available today consists of six desktop processors that all fall under the ‘8 th Generation’ nomenclature, and are built under the codename ‘Coffee Lake’ to designate the microarchitecture and manufacturing process combination.Īll these new processors are desktop parts, meaning they are socketed processors for use in appropriate motherboards featuring the Z370 chipset. There are a number of interesting elements to this launch to be excited about, and a number of factors that raise even further questions, which we will go in to.
