Geil has surfaced with some various designs of DDR5-4800. Teamgroup has also announced DDR5-4800 to be available soon. PNY also has surfaced with their DDR5-4800 offerings. It should not be long before more vendors step up with DDR5 offerings.
The Teamgroup memory kit (TED532G4800C40DC01) comes in a dual-channel presentation, so you get two 16GB DDR5 memory modules for $310.99 which is close to the price of the 32GB of DDR4 in use now.
40-40-40-77 timings mean no real gains over DDR4 outside larger capacity. The CL16 DDR4-3200 is very high performance and the CL number for DDR5 is horrible. The early speed grades are:
- DDR5-4800A: 34-34-34
- DDR5-4800B: 40-40-40
- DDR5-4800C: 42-42-42
JEDEC DDR5 spans to 6400 which is faster than the DDR5-4800 they seems to be the first wave of RAM. Most likely AMD will support the full JEDEC speed grades but what Intel is going to do with DDR5 is an open question. DDR5-8400 is under development and DDR5-12600 is more remote.
No question that DDR4 will improve substantially into 2023 when factories are better able to make RAM chips that can handle the faster transfer rates. SK Hynix figures that DDR5 is expected to be 10% of the global market in 2022, increasing to 43% in 2024 which is consistent with other estimates.
Given the CL16 RAM in use now DDR5 will have to do better to motivate me to yank the motherboard and spend some cash on new hardware. All I really need is a better graphics card but competing against well funded miners makes that a cruel joke.
