Xeon E-2278G vs Xeon Gold 6234: Lower price, higher single thread rating

Xeon E-2278G: cpubenchmark.net/cpu.php?cpu=Intel+Xeon+E-2278G+%40+3.40GHz
Xeon Gold 6234: https://www.cpubenchmark.net/cpu.php?cpu=Intel+Xeon+Gold+6234+@+3.30GHz&id=3518&cpuCount=2
The single thread rating for the E-2278G is 3046 vs 2346 for the Xeon gold and the E-2278G has like half the TDP. Does this mean that if I'm building a rig which wont be heavily multithreaded, I should pick the E-2278G?
Why doesn't the Xeon gold/plantinum line have anything like the single threaded performance of the much cheaper E-2278G?

 

well you compare two different platform, the xeon 6234 is made for LGA3647 while the E-2278G is made for LGA1151, with LGA3647 socket you can go up to 4 CPU where all of them have 6 memory channels while the LGA1151 is only made for single CPU and 2 memory channel, furthermore xeon gold/platinum are made for server and "regular" xeon for workstation use that's why pricing isn't similar and frequency are lower to assure stability.

 

@TheQuentincc hit the main points.

I assume you're going the Xeon route because you need ECC memory ...?

I think the E-2278G supports ECC memory: https://ark.intel.com/content/www/u...eon-e-2278g-processor-16m-cache-3-40-ghz.html

For me, the bottleneck is memory, the E-2278G maxes out at 128GB, and I need a lot more. The Xeon supports 1TB.

@TheQuentincc what did you mean by stability?

 

the higher TDP of the 6234 would be worst case scenario power consumption (including AVX workload I assume), so that's the number you can use to predict power consumption/cooling capacity needed for your server (in datacenter that's a thing), and lower frequency is for stability because they are intended to run 24/7 at 100% utilisation with no error allowed while keeping the power consumption under the TDP
