In the past few years, Intel's product line has always been very stable. Each product is only a small increase in size, and the overall layout is almost unchanged. Now in the whole line of AMD Ryzen, Intel finally opened his step. In addition to adding core / threads from high to low collectors (Pentium has ultra-threaded), the Core i3 series facing the middle and low-end market will also usher in historic changes: support Turbo Boost Rui Frequency acceleration!
In history, the i7 series supports hyperthreading and Turp, i5 supports Ruixing but cut off the ultra-thread, i3 supports super-threaded but cut off Turp, and the water does not commit river water, and go to the eight-generation Coffee Lake, I3 is rising to four At the core, in order to pull the product grade in order to pull the I5 of the six-core six thread, it lost the ultra-thread, but there is still no Turp.
The above is mainly a desktop product, and the notebook is slightly different, but I3 will also have a Turp.
Now, there are two new Core i3-81xxu series, watch the number belonging to the mobile low-voltage version of the eight-generation Core, the biggest surprise is the first time to join Turbo support, and it is probably the first 10nm Cannon Lake family belonging to the legend. !
The first is Core i3-8130u, dual-core four-thread, reference frequency 2.2GHz, Cavity frequency acceleration to 3.4GHz, three cache 4MB, integrated core graphics UHD 620 300-1000MHz, thermal design power consumption 10-15W.
In contrast, the Core i3-7130U frequency of the seven-generation family is fixed in 2.7GHz. Although the reference frequency is low, it can be dynamically accelerated, which is naturally more flexible, especially beneficial to improve the single-threading performance.
In addition, the three-level cache also increased by 1MB, but the energy consumption of variable heat is narrowed, higher.
Then Core i3-8121u, the same as the dual core four-thread, the same as 4MB of three-level cache, "Geekbench, only one 2.21 GHz, but clearly, suggesting that there will be Turbo acceleration.
More critical is that the detection frequency is lower than 18%, the performance of Core i3-8121U is greatly improved than Core i3-7130u, single thread, multi-threads are exceeded by about 25%, no Turbo will definitely do not do it. .
The INSTLATX64 also found that the identity of Core i3-8121u seems to be very special, the CPUID string is 60663, which is clearly different from the past, plus the three-level cache capacity, so it is a new 10nm craft product, after all, INTEL himself Say, 10 nm will be prioritized for mobile platforms.
In addition, Core i3-8121U / 8300U has also opened more instruction sets, including AVX512F, CD, BW, DQ, VL, VBMI, IFMA, and also explaining that the architecture should have changed.
From the positioning, the opponents of them are all the new mobile version of the Ryzen APU in AMD.
