Lexar ARES RGB DDR5-6400 2x16GB vs Lexar THOR Z RGB DDR5-6000 2x16GB 6800 CL34 in detail
True latency
Both kits land on 10.00 ns by different routes: Lexar ARES RGB DDR5-6400 2x16GB at 6400 MT/s at CL32, Lexar THOR Z RGB DDR5-6000 2x16GB 6800 CL34 at 6800 MT/s at CL34. A CAS number counts cycles rather than time, so a higher clock absorbs a looser one and the two arrive together — which is why these spec sheets look different and the memory does not.
Transfer rate
Lexar THOR Z RGB DDR5-6000 2x16GB 6800 CL34 is rated 6800 MT/s against 6400 MT/s for Lexar ARES RGB DDR5-6400 2x16GB — 54400 MB/s per module, against 51200 MB/s. That is peak transfer rate, not access time: reaching a higher clock costs more cycles on each access, which is why the CAS numbers differ too, and why the true latency above is the figure that compares directly.
Price and tracked history
Lexar ARES RGB DDR5-6400 2x16GB is tracked at $1,036.00 — $32.38 per gigabyte — and Lexar THOR Z RGB DDR5-6000 2x16GB 6800 CL34 at $1,125.00, or $35.16. Both are 32GB kits, so the totals compare directly: Lexar ARES RGB DDR5-6400 2x16GB is $89.00 less than Lexar THOR Z RGB DDR5-6000 2x16GB 6800 CL34. At $1,036.00, Lexar ARES RGB DDR5-6400 2x16GB is running 3% below its own 90-day median. At $1,125.00, Lexar THOR Z RGB DDR5-6000 2x16GB 6800 CL34 is running 3% below its own 90-day median.
Kit layout
Lexar ARES RGB DDR5-6400 2x16GB ships as 2 × 16GB and Lexar THOR Z RGB DDR5-6000 2x16GB 6800 CL34 ships as 2 × 16GB — the same number of sticks either way, so both populate a board's slots identically.
Voltage
Lexar ARES RGB DDR5-6400 2x16GB is specified at 1.4 V and Lexar THOR Z RGB DDR5-6000 2x16GB 6800 CL34 at 1.35 V. That is the supply each kit's published profile asks the board for.
Lighting, timings and ECC
On the lighting question: Lexar ARES RGB DDR5-6400 2x16GB is published with RGB lighting, and Lexar THOR Z RGB DDR5-6000 2x16GB 6800 CL34 is published with RGB lighting. On the full timing tuple, the numbers that follow CAS: Lexar ARES RGB DDR5-6400 2x16GB runs 32-38-38-76, and Lexar THOR Z RGB DDR5-6000 2x16GB 6800 CL34 runs 34-45-45-108. On error correction: the catalog does not state whether Lexar ARES RGB DDR5-6400 2x16GB supports it, and Lexar THOR Z RGB DDR5-6000 2x16GB 6800 CL34 is published with ECC support. Whether ECC is worth having depends on the platform as much as the modules — the board and the CPU have to support it too.
Which to buy
Lexar ARES RGB DDR5-6400 2x16GB costs less than Lexar THOR Z RGB DDR5-6000 2x16GB 6800 CL34 at the prices tracked here, and the two are identical on true latency at 10.00 ns. It is the cheaper kit, not the faster one — nothing here suggests it will feel quicker.
