Can someone remind me of Intel's CPU generation codenames?

[AstroBenny]

It seems I've got a little confused regarding what order this stuff goes..

Ivy Bridge e.g. 3770K

Haswell e.g 4770K

Devil's canyon e.g. 4790K

(Broadwell here??) Wait...why no 5770K..?

Skylake e.g. 6700K

Kaby lake?

 

So where does Broadwell E, Broadwell EP and Haswell E fit in to this?

Those come after their respective consumer versions. E are for enthusiast. EP are for servers. They typically have higher core counts, and more PCI-E lanes among other things. 

 

Ivy Bridge e.g. 3770K

Haswell e.g 4770K

Devil's canyon (AKA Haswell Refresh) e.g. 4790K

Haswell E e.g. 5960X

Broadwell e.g. 5775C

Broadwell E e.g. rumored to be a 6950X

Broadwell EP e.g. E5 2600 V4

Skylake e.g. 6700K

Devil's Canyon (refresh) is in between Haswell and Haswell-E. After Haswell-E is Skylake then Kaby Lake. These are only consumer (not server) CPU generations.

Are EP Xeons? and E desktop enthusiast?

Edited my post.

Yes but there are also ivybridge e, ivybridge ep, ivybridge en, and ivybridge ex,and haswell e, haswell ws, haswell ep, haswell ex.

 

All microarchitectures with ep/en/ex/ws are xeons, but they do have differences such as the ex is the e7 xeon line supporting up to 8 cpus on a board, and the ws line which are compatible with mainstream sockets like 1150, and 1151.

Sandy Bridge 2xxx
Ivy Bridge 3xxx
Haswell 4xxx (I'm not breaking out DC since it is still Haswell)
Broadwell 5xxx
Skylake 6xxx

 

Exceptions: the -E versions start number is +1 to their generation. E.g. Haswell-E is 58xx or 59xx. Broadwell-E will be 68xx or 69xx. The -E are cut down from the server chips, which lag consumer chips by quite a long time. I guess they fiddled the naming structure to make the CPUs not sound out of date.

 

The k suffix denotes a regular ratio unlocked CPU. Broadwell didn't have a K, they only released C suffix for Crystal Well, the 128MB eDRAM which improves the iGPU and also acts as a fat L4 cache. The desktop parts are also multiplier unlocked. I guess someone decided calling it CK or KC would be a bit much. Desktop Broadwell was so late I think they just released those processors to say they have released them. Shame, as I really like the performance of the 5675C I have but I have no regrets with Skylake either. The eDRAM performance is roughly comparable in ram performance to dual rank, dual channel 3200.
