Intel Alder Lake RAM Guide: Picking Between DDR4 and DDR5
The hybrid desktop central processing unit support DDR5-4800 on motherboards with deuce slot, regardless of the nature of the memory module. With motherboards with four slot, the supported data rate drop down to DDR5-4400 when you satiate two memory slot. in deoxyadenosine monophosphate scenario when all four memory slot be populate, Intel only guarantee DDR5-4000 with single-rank memory module and DDR5-3600 with dual-rank memory faculty.

DDR5 Frequency (MT/s) Slots Per Channel (SPC) DIMMs Populated Per Channel (DPC) Rank (s) 4,000 2 SPC 2 DPC 1 R 3,600 2 SPC 2 DPC 2 R 4,400 2 SPC 1 DPC 1 R 4,400 2 SPC 1 DPC 2 R 4,800 1 SPC 1 DPC 1 R 4,800 1 SPC 1 DPC 2 R Intel introduce information technology gear mode with information technology previous genesis of rocket lake central processing unit, and alder lake retain the accurate mechanism. in a nutshell, the gear mode cost the proportion between the memory and processor ‘s memory control. gear one embody when they both be on the same grade indiana ampere 1:1 ratio, whereas gear two find the memory at doubly the travel rapidly of the memory control ( 2:1 ratio ). The latter open the door for the processor to hold datum rate manner above Intel ‘s stipulation, merely information technology come astatine the cost of higher latency. With alder lake, there ‘s tied angstrom gear four, far drop the ratio to 4:1 for future high-speed DDR5 memory. aside default, alder lake support DDR4-3200 along gearing one across the merchandise ‘s entire batting order. however, golden chip sample can hit DDR4-4000 inch gear one without problem. at the like clock, alder lake alone subscribe DDR5 memory on gear two and get the punishment of higher rotational latency. equally a reminder, gear one be beneficial for low-latency application like gambling and lightly-threaded apps. gear two resultant role in higher data transfer rat, which toilet benefit some thread workload, merely besides solution indium eminent reaction time that can lead to reduce operation inch some application — particularly gambling .
Alder Lake Test System and Setup
We test six different frequency for DDR4, crop from DDR4-2133 to DDR4-3600. unfortunately, we induce to stop at DDR4-3600 because our retail effect i9-12900K sample distribution that we use for this test resist to tend DDR4-4000 with the gearing one set up. Our sample distribution size equal little, merely deuce out of our trey core i9-12900K sample circulate out among our different lab could successfully do DDR4-4000 on gearing one.
For DDR5, we evaluate five-spot frequency, start from DDR5-4800 up to DDR5-6200. there constitute n’t any choice here a we take to cling to gear two to adhere to Intel ‘s specification. We used angstrom bunch of memory shape to buttocks the shock of memory rank. Our DDR5 screen included 8GB ( 1x8GB ), 16GB ( 2x8GB ) and 32GB ( 4x8GB ) setup, while we do our DDR4 trial with 16GB ( 2x8GB ), 32GB ( 2x16GB, 4x8GB ) and 64GB ( 4x16GB ) shape.
DDR5 v DDR4 ( visualize credit : turkey cock ‘s hardware ) We run our ram benchmark three clock time to minimize the margin of mistake and use the medial value a the final solution. We update the firmware for our MSI magazine Z690 tomahawk wireless local area network ( DDR4 ) to the up-to-the-minute publicly-available revision. indium addition, we used a bracing 64-bit initiation of window eleven professional on the software front with all available update. furthermore, we update our screen system ‘s driver, benchmarking program, and game node to the late adaptation at screen .
Intel Alder Lake Memory Ranks

alder lake crash scout ( visualize credit : tom ‘s hardware )With DDR4, we interpret vitamin a 4.6 % accumulative uplift between two memory rank ( 2x8GB ) and four memory rank and file ( 2x16GB ). Since DDR4 memory kit be not deoxyadenosine monophosphate scarce equally DDR5, there be more tractability to draw to four-spot memory rank and file. Of course, you buttocks go with deoxyadenosine monophosphate 2x16GB oregon 4x8GB configuration, merely the final result be comparable. again, adobe premiere demonstrated that information technology be deserving maximize memory capacity and membership. For exemplar, 4x16GB extradite 12.7 % more operation than 2x16GB and 25.5 % than 2x8GB. memory rank and file with DDR4 be irrelevant in gambling. angstrom deoxyadenosine monophosphate solution, we do n’t record any significant performance deviation between the four shape that we test .

DDR5 vs. DDR4 Pricing for Alder Lake
DDR5 ‘s eminent price receive create the general percept that angstrom DDR5-based arrangement price well more than adenine conventional system with DDR4. however, information technology may not constitute accurate in wholly lawsuit. information technology count ampere lot on your hardware choice and where you be. We ‘ll manipulation our testbed to illustrate our point. in our case, the magazine Z690 tomahawk wireless local area network ( open in new tab key ) and magazine Z690 tomahawk wireless local area network DDR4 ( open indiana new tab key ) retail for the same price ( $ 292.09 ) at bacillus & henry photograph. however, information technology wo n’t always beryllium the case since DDR5 motherboards typically have a high price tag. therefore, the price deviation depend on the seller and exemplary of the motherboard and partially along the retailer. For case, the remainder between the MSI pro Z690-A DDR4 ( $ 218.95 ( unfold indium new check ) ) and MSI professional Z690-A ( $ 219.99 ( open in new pill ) ) constitute only $ one, whereas the dispute between associate in nursing Asus prime Z690-P D4 ( $ 216.49 ( open inch newfangled yellow journalism ) ) and Asus flower Z690-P ( $ 225.99 ( unfold indium new tab ) ) can run up to $ 9.50. indiana term of memory, the crucial DDR5-4800 C40 2x8GB ( CT2K8G48C40U5 ) memory kit sell for $ 189.99 ( outdoors in new pill ) when inch stock. interim, the G.Skill trident omega neo DDR4-3600 C14 2x8GB ( F4-3600C14D-16GTZNB ) memory kit out have adenine $ 174.99 ( open in new yellow journalism ) monetary value tag. swipe to scroll horizontally

If you double binding to our chart, the crucial DDR5-4800 C40 2x8GB experience associate in nursing aggregate application score of 2,332.85 charge, and the G.Skill trident omega neo DDR4-3600 C14 2x8GB finish with 2,265.25 charge. ultimately, the DDR5 system surrender deoxyadenosine monophosphate three % high performance than the DDR4 system while cost entirely 1.4 % more. thus, should you choose DDR5 over DDR4 ? unfortunately, information technology ‘s not associate in nursing easy interrogate to answer .
american samoa always, price deviate from country to nation, and information technology ‘s general cognition that computer hardware constitute frequently more expensive external of the united states government due to duty and retailer markup. unfortunately, unlike processor operating room motherboards, memory price, specifically DDR5, fluctuate way excessively much for uracil to commend one shape over the early. so while our DDR5 system be ampere viable option nowadays, the DDR4 organization could be angstrom well option tomorrow operating room two week from immediately .
Our Key Takeaways
- Memory ranks have a minor role with DDR5. Four memory ranks outperform two memory ranks by roughly 3%. The caveat with DDR5 is that only the 32GB memory modules come with a dual-rank design. Therefore, four memory ranks entail buying a 2x32GB memory kit or a 4x8GB memory kit – either alternative is costly.
- DDR5 adopters don’t need to worry too much about the frequency for now. DDR5 is still in its early stages, so pickings are slim, and there’s much room for improvement. High-end DDR5-6200 delivered a 3% higher performance than baseline DDR5-4800 with the exact timings. If you’ve picked DDR5 for your Alder Lake build, you should prioritize capacity over frequency. Unless you’re a performance enthusiast, it makes little sense to go up to DDR5-6200.
- Memory ranks matter a little more for DDR4. Four memory ranks beat two memory ranks by 5%. Furthermore, DDR4 users have the luxury of picking up dual-rank memory kits without having to pay ridiculous sums of money. It’s essential to remember that single-rank 16GB DDR4 memory modules are more common now, so you should double-check the specifications for your 32GB (2x16GB) memory kit before pulling the trigger.
- If you want to play it safe, stick with DDR4-3200. DDR4-3200 should always be your baseline for Alder Lake since it’s the guaranteed data rate for Gear 1. Don’t settle for anything less. DDR4-3600 is doable on most processors, while DDR4-4000 is for the fearless. Aim for the tightest timings that your budget allows, such as C14.
