Intel i5-8250U or AMD Ryzen™ 3 5300U?

[Okonkwo]

I was deciding what laptop I should be getting, and I was curious which of the two CPU processors are better. I know both aren't the best for gaming, but which is a better option?

The Ryzen is all around better
The CPU also has a higher base clock and slightly higher boost clock

So the Ryzen is likely the better choice, assuming you can get it with 3200mhz RAM or there abouts and at least 16GB

Not to mention MUCH newer.

Passmark
Ryzen 5300U - 10291points
Core i5 8250U 5966 points

video peeformance
Ryzen 5300U is equal to GTX 960M
Core i5 8250U is between Geforce 910M and Geforce 920M
i.e. 2 - 2.4x better is Ryzen 3 5300U

so Ryzen 3 5300U is better

r3 is a weaker cpu with a better igpu
i5 is a better cpu with weaker igpu

depends on your needs
for gaming take the r3, office or other work go with the i5

I came to the conclusion years ago that the U on intel chips means Useless for gaming. Single thread speed equal to that of an i7-2600 released in 2011. So that's a Do Not Buy for gaming regardless. The amd is about 25% better but it's still slow - about the same as a 2016 i7.

But that makes the amd better for all apps as both cpus are 4c/8t.

Laptops with a 4800H would be a heck of alot better.

The 5300u is much better core wise than the 8250u.

Laptops with Intel 8th Gen will be sorely outdated. Not just the CPU but everything else on the laptop as well.

Consider Laptops with either Intel 10th or 11th Gen CPU
or ones with Ryzen 4xxx or 5xxx series; but a 5300U is very weak. Ryzen and Intel cpus that end in "U" should be avoided really.

Also look at ones that have at least a GTX 1660 or RTX 2060

Ryzen 5300U is a very very good CPU !
as for CPU performance
Ryzen 5300U is equal to i5 9500F

Well, that isn't their intended role. U (ultra low voltage) CPUs are just lower voltage chips, which usually means lower clock speeds and/or limited or even no boosting. Yes, they are therefore slower than non-U CPUs (only when comparing like for like) as they serve the exact literal opposite purpose to those that are there for raw performance.

That's also what happens when CPUs advance slowly in single core speed for the better part of a decade. There's like a two thirds to four fifths improvement (not really even twice as fast) between the Sandy Bridge you mentioned from a decade ago and the 10th generation stuff, and realistically the IPC increase itself is probably a bit lower than that because clock speeds going up account for some of that single core increase. Naturally, mobile offerings are a bit slower, and U models more so.

On the other hand, it's impressive to match that with such low power use, even if it comes years and years later, given the slow rate of increase.

the purpose of applying ultra low voltage is one , just to lower the power consumption and hence the chip to run cooler . it has nohing to do with how high the core speed is

Yes, it's for lower power draw and battery life, mostly, but it goes hand in hand with a lower clock speed needing lower voltage. There are U CPUs with "not quite as low" of clock speeds but they are definitely performance limited due to having to fit into a lower voltage envelope, and part of that is achieved by keeping the clock speed lower, so they do tend to have lower clock speeds. My Haswell one is only 1.7 GHz and lacks boost entirely.

look at the benchmarks

What benchmarks, and for what purpose? All I replied was that U CPUs tend to have lower clock speeds as part of fitting within a given voltage envelope. I wasn't talking about performance in my last post.

That is incorrect. Voltage has everything to do with frequency.

Silicon lottery determines how much voltage is necessary to run a target frequency, better silicon needs less, worse silicon needs more.

Ryzen CPUs are very inconsistent with Precision Boost because the chip scales voltage and frequency, some scale better while others scale worse. If voltage didn't matter, they would all run basically identically.
