    Apple Ignites the Industry with the M1 Pro and M1 Max

    I don't understand the 400 GB/s bandwidth. I understand that the M1 Max got 4 memory channels and with a bandwidth of about 50 GB/s for each DDR5-6400 I get a total bandwidth of 200 GB/s. Do Apple sum write and read bandwidths?

    AMD EPYC 7282 Benchmarks and Review

    In this review it looks like the 7282 performs almost as well as the 7302. Looking at CPU2017fp rates at spec.org tells a very different story. In 7 of the 13 testcases the 7282 is beaten with a significant margin (~x 2) by the 7302. Even the old part 7281 beats the new 7282 with a large margin...

    X11-DPHT Memory Recommendations

    If the processor in question just supports up to 2400 MHz, then chose option 2 ;). For processors supporting 2666 MHz, I think, the two memory options will perform nearly the same. Based on https://lenovopress.com/lp0697.pdf the bandwidth scales with frequency. When two dual rank DIMMs are...

    X11-DPHT Memory Recommendations

    Lenovo has publiced reports about various memory configuration. Even though that is not SuperMicro, the memory controller is the same. Se https://lenovopress.com/lp0697.pdf for a comparison between single and dual rank memory. The conclusion is on page 11. (use dual rank) Lenovo has also looked...
