AMD's super-cheap old Ryzen 3 CPUs get an update because it's all out of 14nm wafers

AMD is quietly upgrading some of its first generation Ryzen processors from using the old 14nm process to a 12nm process. Updated 12nm versions of the hex-core Ryzen 5 1600 have already been seen in the wild, and now the quad-core Ryzen 3 1200 has joined it. 

Throw in the fact that this updated chip can be picked up for as little as €55 and it suddenly looks like one of the best value gaming CPUs on the market right now. We reached out to AMD for the skinny behind the recent update.

"The newer Ryzen 3 1200 is a 12nm, 2nd-gen Ryzen part we created to replace the 1st gen Ryzen 3 1200," AMD told us. "We can no longer make the original, as the 1st Gen model is based on old 14nm wafers that we can no longer supply. 

"So we created the updated part to service markets where the Ryzen 3 1200 is still very important and popular. We didn’t want to confuse the market with another part number and since there are no down-sides for the consumer, we were OK with keeping the name."

The architecture has been revised for the newer versions of these chips as well. Essentially you're getting a Zen+ version of the first generation chip, for not much cash at all. In real terms this means you get slightly better performance out of it, as with Zen+ the boost levels are governed by core load, current, and core temperatures. That differs from the original Zen, where the boost was governed chiefly by the number of cores used. Cache access is also improved with the newer Zen+ as well. 

Basically, it's just a better chip all round.

But how do you know you're buying the newer 12nm version of the Ryzen 3 1200 over the original 14nm SKU? By the OPNB (Ordering Part Number Boxed), which for the new CPU is YD1200BBAFBOX as opposed to the original YD1200BBAEBOX, which explains why you may see the newer CPU referred to as the Ryzen 3 1200 AF. 

Should you be rushing out to buy one of these newer Ryzen 3 1200 then? Possibly. If you can find them cheap enough wherever you are, then there's a lot to be said for these capable CPUs. It's not going to be the fastest CPU you've ever put in a machine, and don't forget you'll need a dedicated graphics card as these aren't APUs, but if you can find one for $55 or thereabouts, then in terms of raw performance it's almost impossible to beat. 

If you do manage to get your hands on the newer Ryzen 3 1200 (12nm) then you may need to update the BIOS on your X370 or B350 motherboard, as this is a Pinnacle Ridge chip as opposed to the original Summit Ridge. 

There's another slight problem here as well, and that is that AMD has just announced that the $100 Ryzen 3 3100 is on the way very soon, which looks like a very tasty budget offering.
