Intel’s approaching thirteenth Technology Raptor Lake processors embrace DDR5 and DDR4 reminiscence. However, preliminary benchmarks reveal that the previous is best for maximizing efficiency on the brand new hybrid desktop chips.
Raptor Lake could also be simply down the road as latest rumors declare that Intel is allegedly eyeing an October 7 launch date. The preliminary rollout will embrace the high-end Okay-series SKUs, such because the Core i9-13900K, Core i7-13700K, and Core i5-13600K, along side the top-tier Z790 chipset. Though we haven’t any official affirmation on the specs, the Core i7-13700K has popped up a couple of occasions in several benchmarks.
The Core i7-13700K is a 16-core processor comprising eight Raptor Cove Efficiency cores (P-cores) and eight Gracemont Effectivity cores (E-cores). The Raptor Lake chip additionally has 30MB of L3 cache and reportedly flaunts a 3.4 GHz base clock and 5.3 GHz increase clock. A latest Geekbench 5 submission (opens in new tab) confirmed that the Core i7-13700K outperforms AMD’s flagship Ryzen 9 5950X. Nevertheless, {hardware} sleuth Benchleaks (opens in new tab) has uncovered a new submission (opens in new tab) that signifies that the DDR4 reminiscence was holding the Raptor Lake chip again.
The Core i7-13700K with DDR4 system used the ASRock Z690 Metal Legend WiFi 6E, whereas the DDR5 testbed had the Z690 Metal Legend WiFi 6E/D5. The 2 motherboards are similar apart from the reminiscence slots. The DDR4 system used DDR4-3200 reminiscence, and the DDR5 system with DDR5-5200 reminiscence, the native, supported information charges for Raptor Lake. From the Geekbench 5 entries, we all know that each programs had 32GB (2x16GB) of reminiscence; due to this fact, the outcomes are comparable. Sadly, Geekbench 5 would not go into particulars, such because the mannequin of the reminiscence modules or the timings. Consequently, we can’t know if the 16GB DDR4 reminiscence modules are single-rank or dual-rank.
Intel Core i7-13700K Benchmarks
Processor | Single-Core Rating | Multi-Core Rating |
---|---|---|
Core i7-13700K + DDR5-5200 | 2,069 | 19,811 |
Core i7-13700K + DDR4-3200 | 2.090 | 16,542 |
The outcomes confirmed that DDR5 did not do a lot for the Core i7-13700K by way of single-core efficiency. The DDR5 system was 1% slower than the DDR4 system, but it surely’s inside the margin of error. Nevertheless, the DDR5 system delivered as much as 20% increased multi-core efficiency. That is a fairly vital efficiency delta.
DDR5 pricing has been bettering. The pricing hole between DDR5 and DDR4 will ultimately get smaller over time, but it surely’s unlikely that DDR5 will price the identical as DDR4. The previous is far more costly to fabricate and incorporates a extra intricate design with added elements like energy administration built-in circuits (PMIC) and VRMs.
DDR5 reminiscence can increase Alder Lake’s general efficiency, relying on the workload. Nevertheless, in contrast to Alder Lake, which wields Golden Cove cores, Raptor Lake makes use of Raptor Cove cores, which might behave otherwise to reminiscence speeds. Whereas the preliminary outcomes with DDR5 look promising, we might should conduct thorough assessments to go judgment on whether or not DDR5 is definitely worth the premium over high-performance DDR4.
