I recently bought a Dell Inspiron 14 with Ryzen 5500u and executed the Geekbench 5 benchmark. Performance really depends on the Ram configuration : having 2 RAM sticks (dual channel) adds around 10 to 20% of performance compared to a single RAM stick configuration. With stock 8GB RAM, a single stick of CL22 3200Mhz of DDR4, I was getting 1061 for single core performance and around 3960 for multicore. Upgraded to 16GB of RAM, 2x 8GB of CL20 3200Mhz (Kingston FURY), getting 1116 in single core and 5784 multicore!

To be fair, you should be comparing between1x8GB vs 2x4GB as then you'll be comparing the difference between single and dual-channel. Vs 8GB single vs 16GB dual as 2 variables are being adjusted here.

Go for amd ryzen 5500 u, more cores and more threads increases the performance

Both are basically the same architecture. But Ryzen 5 5500U has 6 more threads. So ultimately it will perform better in multi-core-threaded operations. So I suggest going with Ryzen 5 5500U if get that at a similar price point to Ryzen 5 4500U.

I think you should choose AMD® Ryzen™ 5 5500u. it's better than 4500u. Even, though both of them have 6 cores Ryzen 5500u has 6 cores and 12 threads... Even it's newer and has more features.

The 4500u was a mind blowing cpu on launch to the extent it thrash almost all 10th gen mobile cpu Intel had to offer but now it looks like Intel got the message and has responded with the 11th gen Tiger lake which is roughly equal to AMD 4000 series counterpart. Compared to that I can hardly see a leap in performance from the 4500u to the 5500u. In fact the newer 5500u is more of a downgrade than an upgrade to the 4500u by having a lower base frequency and memory size, it's more of a let down than adding some few threads and minor tweaks. AMD decided to screw this one up giving Intel more pace to catch up(which Intel won't squander lol). As for the 5500u, it's a shame it didn't live up to the hype and you probably will still be better off with the 4500u or Intel's 11th gen.

It is NOT a downgrade at all. Lowering the base frequency enables the 5500 squeeze more time out of the battery on idle -> light load while still maintaining the max frequency during heavy work loads. As for the reduction in maximum memory supported, absolutely nobody that buys a laptop (especially those in the price point featuring a Ryzen 4500u or 5500u) ever upgrades beyond 32GB. All the benchmarks show that the decisions taken lead to a better overall product. While it might look marginal per benchmark, in typical usage, the performance improvements add up to a noticeably better user experience.

Isaac, @Isaac I agree with you. It's not a downgrade.

beside (maybe) the extra 6 threads, nothing new about the newer 5500u. only cosmetic performance improvements. same zen2 tech, same bellow-intel single-core performance. (in comparison, lets say the 1135g7 i5). the new "hype" is going down in my opinion, and only for lack of effort from the amd side.

So i5 1135g7 is good in single core performence
