DELTA RGB 6400MHz CL40 DDR5 Review – How much better is it than DDR5 5200MHz or DDR4 3600 for Gamers?
We were eager to compare the T-FORCE DELTA RGB 6400MHz CL40 DDR5 2x16GB memory kit that TeamGroup sent BTR for review with our 2x16GB T-FORCE DARK Z 3600MHz CL18 DDR4 and 2x16GB T-FORCE VULCAN 5200 CL40 DDR5 kits. DELTA is available at Newegg for $539.99 which is above list price ($399.99) but currently less expensive than at Amazon. Is it worth it for gaming performance?
We used a full set of benchmarking tools and 31 games to see if gamers should choose DDR5 over DDR4 for Intel’s newest Z690 CPU platform and to see if faster DDR5 speeds make a performance difference. This is the second installment of BTR’s memory review series that compares DDR4 with progressively faster DDR5, and it will later focus on latency to also measure its effects on gaming performance.
Last year, BTR ran an extensive set of tests comparing DDR4 3600MHz CL18 with CL16 and the performance results were very similar for gaming, so our T-FORCE DARK Z 3600MHz CL18 2x16GB kit is representative of today’s fast DDR4. We started over with new benchmarks and have updated our testing tools to focus narrowly on DDR4 3600MHz CL18 versus DDR5 6400MHz CL40 versus DDR5 5200MHz CL40. We use an i9-12900KF on an ASUS Prime Z690 P-D4 Z690 DDR4 motherboard to compare memory performance against an ASUS ROG Maximus Apex Z690 DDR5 motherboard.
The VULCAN 5200 CL40 black kit (at Amazon for $359.99) has a MSRP of $349.99 that we are comparing to the DELTA DDR5 6400 kit (at Newegg for $539.99). However, the T-FORCE DARK Z 3600MHz CL18 DDR4 2x16GB kit sells for $115.00 on Amazon so there is a large difference between DDR5 and DDR4 pricing. The MSRP of the DELTA RGB DDR5 6400 2x16GB kit is evidently $399.99 although it is $539.99 at Newegg, and will update this review when we hear back from TeamGroup.
Since no motherboard supports both types of memory, most gamers have a choice of using their current DDR4 memory on a Z690 DDR4 motherboard or buying new memory for a Z690 DDR5 motherboard. When BTR originally upgraded its flagship PC from an i9-10900K to an i9-12900KF, we picked a solid midrange ASUS Prime Z690-P D4 board for our DDR4 3600 memory. We then purchased an ASUS ROG Maximus Apex Z690 DDR5 motherboard for this memory review series and will overclock our DELTA RGB DDR5 to see if we get any additional performance.
From our testing with Ivy Bridge, Haswell, Skylake, Coffee Lake, and Comet Lake platforms, using faster DDR over slower DDR brings only limited performance improvements for a few CPU-dependent games. However, we found that using faster memory brings extra overall performance gains for many other tasks and applications and we will compare overall DDR5 6400 performance with DDR5 5200 performance and versus DDR4 3600 using multiple synthetic and real world applications.
Our 2x16GB review sample of T-FORCE DELTA RGB 6400MHz CL40 DDR5 desktop memory is a high speed high-capacity gaming memory kit for Intel’s 12th Generation CPU platform. Here are the three memory kits that we are comparing:
- T-FORCE DELTA RGB PC5-51200 6400MHz DDR5 CL40 2x16GB kit
- T-FORCE VULCAN PC5-41600 5200MHz DDR5 CL40 2x16GB kit
- T-FORCE VULCAN DARK Z PC4-28800 DDR4 3600MHz CL18 2x16GB kit
Just like with video cards, predatory resellers have been buying large quantities at MSRP to resell them at inflated prices to turn a profit. If you want DDR5, please don’t buy from them. Fortunately, DDR5 supply is increasing and it is possible to buy at or near MSRP now.
Testing Platform, Product Specifications & Features
Our testing platform is a recent clean installation of Windows 11 Professional, using an Intel Core i9-12900KF at stock settings using either a 1) ASUS Prime P-D4 Z690 motherboard for DDR4 benchmarking or 2) an ASUS ROG Maximus Apex Z690 motherboard for DDR5 benching; a 2TB T-Force C440 CARDIA NVMe PCIe 5,000MB/s SSD, and with either: (1) 2x16GB T-FORCE DELTA RGB DDR5 6400MHz CL40; (2) 2x16GB of T-FORCE VULCAN 5200MHz DDR5 CL40; or (3) 2x16GB T-FORCE Dark Z DDR 3600MHz CL18 memory. We use an RTX 3080 Ti Founders Edition at stock clocks as befits a high-end PC. The settings, benchmarks, testing conditions, and hardware are identical except for the three memory kits and their respective motherboards being compared.
Voltages are set at XMP profile defaults of 1.35V for the DDR4 3600MHz memory and DDR5 6400MHz memory, and 1.25V for the DDR5 5200MHz memory. Command Rates are also set by their respective default XMP profiles in the BIOS at 2T. The default XMP Profile timings of the T-FORCE DARK Z 3600MHz is CL18-22-22-42, the T-FORCE DELTA DDR5 6400MHz is 40-40-40-84, and the T-FORCE Vulcan DDR5 5200MHz is CL40-40-40-76.
There are several variants of DELTA RGB DDR5 as TeamGroup’s chart shows.
