The upcoming 12th generation wave Alder Lake There are rumors that Intel processors support DDR5 and DDR4 memory.However, the new UserBenchmark was submitted by Tum_Apisak, Indicating that if paired with the latter, Alder Lake’s performance may be affected.
According to reports, the Alder Lake sample has 16 cores and 24 threads, which is a The configuration we have seen forward. Remember, Alder Lake is composed of Golden Cove and Gracemont cores, but only the former has hyperthreading, so the chip should have 8 Golden Cove cores and 8 Gracemonet cores.
Today’s submission marks the second appearance of the 16-core Alder Lake chip in UserBenchmark. This sample It seems to have a 1.8 GHz base clock and a 3.65 GHz average boost clock.This Previous sampleOn the other hand, they have the same basic clock, but the average boost clock is lower, with a peak value of 3.05 GHz.
Given the number of cores, the engineering sample may be Core i9-12900 or Core i9-12900KObviously, faster chips will provide better memory performance. Since we are not sure whether the two Alder Lake samples are the same processor, we recommend adding a bit of salt when viewing the results.
Intel Alder Lake RAM benchmark test
|Kingston DDR4-3200 2x8GB||Micron DDR5-4800 2x8GB|
|Single core read||15.4||15.4|
|Single core write||30.2||31.4|
|Single core hybrid||22.1||22.4|
The DDR5 platform consists of two Micron DDR5-4800 memory modules, each of which is 8GB. The C8C1084S1UC48BAW part number did not produce any results. If the memory modules comply with the JEDEC specification, their CAS latency (CL) should be 40.
On the other hand, the DDR4 platform uses a pair of 8GB Kingston HyperX Fury DDR4-3200 memory modules. We could not find the product page for HP37D4U1S8ME-8XR, and there are several lists that indicate that these may be OEM memory modules.
DDR4-3200 is 24% higher than DDR5-4800 in the read test and 20% higher in the write test. However, the performance of the latter in the hybrid test was improved by 5%. However, the performance difference in the single-core test is not big. The read test did not change, but the write and hybrid memory performance of DDR5-4800 increased by 4% and 1%, respectively.
DDR5 performed best in the latency test. The memory latency of Alder Lake with DDR5-4800 is reduced by 36%.
Intel’s Alder Lake processors may land in late 2021 or early 2022. In addition to the rumored DDR5 support, heterogeneous chips can also adopt the high-speed PCIe 5.0 standard. AMD replaces Intel on the list Best CPU Therefore, even before the launch date, people had high hopes for Alder Lake.
