Hi everyone !
Yet again another point that caught my eye with Ryzen 4000 series.
I found various ultrabooks coming out with Ryzen 7 4700U. However when comparing the performances of this processors with other 4000 series CPUs I got a bit confused !
The 4700U looks very similar to 4800U without the SMT(simultaneous multithreading) and with a slightly less performant GPU. The 4700U has 8 cores / 8 threads while 4800U offers 8 cores / 16 threads. At this point I can understand that 4800U should perform much better at multi-core computing as it can be seen on benchmarks (cpubenchmark.net / cpu-monkey).
Even if at this point I wonder if it is really justified for someone to go for 4700U while the price difference with 4800U is not that big, things become really weird when I compared Ryzen 7 4700U with Ryzen 5 4600U. The Ryzen 5 4600U has 6 cores/12 threads and it gets 3% less performance at single-threading but performs better than Ryzen 7 4700U at multi-core processing by 7% while it is cheaper than 4700U !

So I'm really wondering why did AMD commercialise the 4700 ? Is there any technical reason behind this or it is only a marketing strategy ?
Thank you in advance !
