Ask HN: Ryzen 5 vs. 6

2 points by meravita 4y ago

I am currently undecided between two HP notebooks. A ProBook with an AMD 5625U and an EliteBook with and AMD 6650U Would you say the EliteBook was the wiser choice or does the newer processor not really make that difference? Thanks

Two things: - Yes, the 6650U is much better. It has newer graphics, newer video encode/decode, better io, more power saving features, support for faster memory, integrated wifi... pretty much the only thing thats the same is the specs of the cores, which is why it looks so similar on paper. - *BUT* AMD butchered the 6000 series naming scheme. Some of the 6000 chips are rebranded 5000 and 4000 chips. If you find another 6000 model you like, you should look it up before assuming its "new."

  Thanks, though the performance seems to be almost the same https://nanoreview.net/en/cpu-compare/amd-ryzen-5-pro-6650u-vs-amd-ryzen-5-5625u https://nanoreview.net/en/cpu-compare/amd-ryzen-5-pro-6650u-... Shouldn't there be a clearer difference if the processor really is better?

    Dont trust automated reviews, trust notebookcheck, who is probably the most thorough laptop reviewer out there.: https://www.notebookcheck.net/AMD-Ryzen-5-PRO-6650U-Processor-Benchmarks-and-Specs.615520.0.html https://www.notebookcheck.net/AMD-Ryzen-5-PRO-6650U-Processo... Again, the CPU is similar, but everything else on the 6000 series is a straight upgrade.

      That seems to be a difference of 3.1% https://www.notebookcheck.net/AMD-Ryzen-5-5625U-Processor-Benchmarks-and-Specs.590122.0.html https://www.notebookcheck.net/AMD-Ryzen-5-5625U-Processor-Be... So the performance is similar, right?

        Yes but everything else (battery life, USB, wifi, graphics performance in the browser, video playback, memory bound workloads, probably fan speed) is going to be better on the 6000 series. Of course the key is price, as always, so I guess the benefits depend on how much more expensive the elitebook is.

Also, I hate to sound like a spambot, but before you pull the trigger, I suggest taking a look at this thing: https://www.bestbuy.com/site/asus-rog-zephyrus-14-wqxga-120hz-gaming-laptop-amd-ryzen-9-16gb-ddr5-memory-amd-radeon-rx-6800s-1tb-pcie-4-0-ssd-moonlight-white/6494639.p?skuId=6494639 https://www.bestbuy.com/site/asus-rog-zephyrus-14-wqxga-120h... The Asus seems to be the same price as that elitebook in the US, but (speaking from personal experience) it is built like a macbook and is hilariously powerful for a 14" laptop, even if you dont need the huge GPU. It also has a good linux community, and the battery will almost certainly outlast the elitebook in a power saving mode.

  Thanks, though 1400 would be a bit beyond my budget. I'd also not need a dedicate GPU - I mostly want a quiet device :)

    I think I linked the wrong one, its only $1300. And it can run fanless. But yeah if you found the elitebook for a discount ($1000?), thats better value.
