Overclocked AMD EPYC Rome 7742 dual socket tops Corona bench, beating Intel Xeon Platinum 8280L setup by 10 percent

[Redaktion]

A user over on the Chiphell overclocked a dual socket engineering sample setup of the AMD EPYC Rome 7742, topping the Corona benchmark and leaving Intel's Xeon Platinum 8280L in the dust.

Intel has very steep prices on high-end Xeons because they support up to 8 socket configurations. Not because of monolithic design.

Support for multiple sockets is very, very expensive. As in they can take you to the cleaners. If you're unfortunate enough to need 8 sockets, they've got you by the balls and they're going to milk you. You can check 8 or 16 core versions which should be available across the range and you can see the steep premiums you pay for 4 or 8 socket support for otherwise the same CPU.

Unfortunately, the highest core count chips are only available in 8 socket versions with astronomic prices. With one exception (AFAIK), the 28 core W-3175X. Which proves my point. It costs a fraction compared to the 8 socket capable Platinums. Before the discounts, Intel was asking $3k for it. I think even the cheapest 28 core Platinum was over 10k. The 8280L is like 16k. More than five times the price.

I vaguely recall AMD claiming that chiplet approaches saves them about a half at higher core counts (16 and above). And what we pay isn't just the cost of silicon. Curves looked pretty much the same. One was just twice as steep for twice the cost.

And if anyone is wondering why is the 8280L that much more expensive, L means it supports up to 4.5 TB of RAM instead of the standard 1 TB. If you need that much RAM, it's another trip to the cleaners. :-)

Also, it's funny to put "dual socket setup" under a picture showing a single socket motherboard with one CPU cooler.
