AMD launches Ryzen Mobile 7 2700U & 5 2500U with Vega Graphics

[USER8000]

I had a quick look at the Cinebench R15 scores,from Reddit,which were ~130 for single core and were ~590(average of the two scores) for multicore:

Now look at the score from the Anandtech review of the 35W TDP Core i7 4765T:

The performance profile is very similar in both benchmarks but in a 15W TDP. No doubt Intel has better single core performance as they have better IPC with their latest and greatest,but that level of CPU performance is still solid for general usage. OTH,to see how far AMD has moved on from Bulldozer look at the FX8350 scores. The Ryzen 5 2500U is marginally slower in Cinebench R15 multi core score,but is more than 35% faster in the single core score,and the FX8350 is a 125W TDP CPU.

So with the Ryzen 5 2500U they have combined the graphics performance of a 95W TDP desktop A10 7870K with better performance for most tasks than a 125W FX8350,and combined this into an APU with a 15W TDP. This is from user testing of actual retail units,not any cherry picked review units. It is not even the top model as the Ryzen 7 2700U is probably a better bin,with higher clockspeeds and more shaders.

Responsiveness on a modern CPU by being a couple 100MHz faster is a joke.

It's not maximum frequency, but time needed to go from idle to maximum frequency. For example, Intel Speed Shift: https://images.anandtech.com/doci/10959/1-7.png

Anyone knows if someone has mini PC (like NUC) in the pipeline using these chips ?

 

[kgor93]

How are AMD chips with virtualization? More cores seems like a dream for that.

Definitely what I'm hoping for!
So far there's only a couple chips known, like the i7-8705G, but the early reports just keep looking better and better!

This bodes well for the 25W chassis and the desktop APUs next year. The desktop chips won't be limited to 2400MHZ DDR4 and can be overclocked.

The way RAM prices are going, pairing a budget APU with fast memory seems like a losing strategy as far as getting the best bang for your buck.

The way RAM prices are going, pairing a budget APU with fast memory seems like a losing strategy as far as getting the best bang for your buck.

Last time I checked if you built an Intel system you also need DDR4,and plenty of people use 2666MHZ and 2800MHZ DDR4,and you can overclock RAM on the desktop. Even the Intel Coffee Lake CPUs do prefer faster RAM if you can use it.

Now if AMD can match a desktop A10 7870K with high end 2400MHZ DDR3 in a 15W TDP environment,what do you think will happen when the same CPU is in a 65W to 95W environment,where the GPU can boost higher and with something like 2666MHZ or 2800MHZ DDR4?

The APUs were held back as much by the weak CPU as much as the memory bandwidth,so even on the CPU side the desktop versions will have a higher clocked CPU.

Raven Ridge will also have a much better memory controller than Bristol Ridge.

In dual channel,even 2400MHZ DDR4 will easily have double the memory bandwidth on Raven Ridge when compared to Bristol Ridge.

other than slightly more performance at a higher price, what is the difference between the R5 & R7? since they both draw the same 15W, i would assume that the R7 would run hotter so perhaps would require fan cooling ? i am looking forward to replacing my 6 year old A10 4600M laptop with a RR ultrabook once they become more widely available-hopefully in January 2018.

Not sure what the 8705G would have to do with the thread topic or with the question you responded to? Thread and question are about Ryzen mobile chips, not about Kaby Lake G.

A review

No surprises. CPU benches neck and neck with Intel.

GPU benches way ahead of Intels IGP.

GPU benches way behind MX150, NVidias lowest end dGPU for laptops.

Battery life is not that great, but hard to compare between different laptops.

Battery life is not that great, but hard to compare between different laptops.

Battery life in video playback is shorter even than what I was expecting May be in part due to the configuration with a HDD, but it is so short I'd guess power saving features are not fully in place yet. Awaiting for further benchmarks, specifically- it would be interesting to see battery life in browsing. The review said both 8250U+MX150 and Ryzen 2500U pulled 9W at idle- but I guess that was measured at the socket- which can mean very different results when different PSUs are used. Some PSUs draw 6W by themselves..

P.S. nVidias lowest end dGPUs are MX130 and MX110.

 

[PhonakV30]

so Ryzen mobile R5 2500U consumes up to 25w. still behind Geforce MX15 (46~50w - Witcher 3 Ultra this link ) , Result is impressive.

 

[USER8000]

If the Ryzen 5 integrated graphics can produce that level of performance,then what about the Ryzen 7 integrated graphics which has 25% more CUs and a 20% uplift in clockspeeds??

On desktop with fast DDR4,Raven Ridge on the desktop has the probability of having very solid entry level graphics performance.

 

[ZGR]

The VLC playback test may have some flaws. If GPU acceleration is not enabled (by default) the CPU will remain turboing at max boost, severely lowering battery life.

With Windows 10's default video player being far more efficient than VLC, they should redo the test using that to see if it effects clockspeeds during playback. Or even enable GPU acceleration in Chrome and test using that. Without GPU acceleration, all dGPU laptops are severely hurt in this test.

It is so easy to monitor this stuff kinda disappointed that they didn't bother looking into the poor battery life.

But overall, Ryzen mobile deserves to be put in a far more expensive chassis. I like how this is a sub $500 laptop, but Ryzen mobile can also be in an expensive Ultrabook-like notebook with far better build quality. Hope to see some more reviews!

 

[PeterScott]

P.S. nVidias lowest end dGPUs are MX130 and MX110.

First I heard of those. A quick search says they are old re-branded Maxwell parts.

So the MX150 is the lowest end Pascal laptop part.

Rebranded or not- they are part of nVidia's current MX dGPU lineup, and actually the latest addition to it. Also- they should be about as fast as Raven Ridge in 15W and 25W configuration, so definitely belong in this conversation.

MX150 doesn't consume 46-50W.

 

[Abwx]

77W at the main for a 8550u + MX150 combo...

[PhonakV30]

MX150 doesn't consume 46-50W.

then how much ? give me a link, did you read my link ?

 

[Qwertilot]

Less Notebook check itself claims 25-30w, but 46-50 isn't that plausible. The desktop 1050/ti are <75w cards - around 50w mobile - and that's a big jump upwards vs the MX150.

 

[Dufus]

Took me a while to find
Report of an i7 8550u pulling up to 44W although not sustainable for long periods.

Also FWIW my DT 1050Ti can pull 100W but then that is OC'd.

 

[beginner99]

Well at least all laptops are tested the same and hence the other laptops do not seem to suffer from this flaw.

We can argue all around this but it is a very bad aspect of RR if it isn't fixed ASAP. Personally I would hold off buying an RR based laptop until this is fixed or go with intel. (assuming they are priced the same but if AMD lowers price they are in the same boat again as always)

 

[USER8000]

This might explain it:

https://www.reddit.com/r/Amd/comments/79xvot/amd_raven_apus_leave_behind_uvd_unified_video/

UVD has been replaced by VCN in Ryzen Mobile. If the drivers are not upto scratch or software does not recognise it,power consumption is going to be high.

 

[Zucker2k]

Did someone mention power?
