When it comes to improving performance across all generations of processors, vendors love to talk about IPC (instructions per clock cycle) as the true efficiency of the CPU. For example, the performance of the future 5.5ghz CPU is 10% better than that of the current 5GHz CPU, or the future 20-thread CPU is 10% better than that of the current 16-thread CPU at the same level. Is its core stronger, or is it flat or even backward?
The best way to compare true CPU efficiency is to look at same-frequency, same-thread configuration performance. You say what? Don’t believe that an architecture upgrade will lead to a loss of efficiency? Not long ago, the Pentium 4 was always criticized for its strong performance. The problem lies in efficiency. The core architecture capability is definitely not really improved by forcing high frequency to achieve high performance through ultra-high power consumption and other methods.
A recent test from BullsLab, an overseas we media, has revealed another period of CPU insider, that is, those generation cores under the 14nm process, how much the efficiency of the architecture under the dazzling frequency increase, hidden core growth. This test was all set at 4.5ghz with 4 cores and 8 threads, using a CPU-sensitive game engine and a lower resolution test, which is a true core efficiency comparison.
Do you see any patterns? If real efficiency gains every two generations are roughly what we’d expect, the overall decrease in core 11 efficiency may come as a bit of a surprise to many. The reason is simple: it’s actually a generation product forced by its mature rival Zen3 architecture, which has had to ramp up its frequency in order to maximize performance against it, while quietly sacrificing some efficiency for the sake of stable high frequency.
Except for some special circumstances, you won’t consider buying the core 11. But these tests on the current Intel product development or some guidance, such as in accordance with the rule of two generations of real efficiency improvement, and then look at the current has been disclosed 13 generation core is to win the situation of high frequency, has 12 generation core partners really do not worry about upgrading oh.
