Analysis from The Stilt:

https://forums.anandtech.com/thread...rmance-unveiled.2533111/page-54#post-39301964

Some of my personal thoughts and experiences on Raven:

Based on the results of my test suite, the IPC of Raven varies between -4.8% - +2.8% compared to Zeppelin. The average difference being ~1.5% improvement. The difference is most likely a result of the changes made to the L2 & L3 caches, rather than the changes made to the actual Zen CPU cores themselves.

The early rumors were correct and Raven does in fact have a significantly lower L2 cache latency than Zeppelin does. The L2 cache in Raven has 12 CLK latency, whereas the L2 latency for Zeppelin is 17 CLKs. The L2 caches in Zeppelin never posed a limitation of any sort to the Fmax, so considering the halved L3 cache in Raven, getting rid of the “slack” in the L2 latency was a smart and most likely a highly beneficial move.

It is hard to tell exactly how small or large the penalty from the halved L3 cache is, as the L2 has been altered significantly at the same time. Generally, however the performance hit from the halved L3 cache varies between small and non-existent. Workloads which hit the > L1 caches hard, such as Bullet Physics library perform < 5% worse on Raven than on Zeppelin, which is equipped with twice the L3 cache per core. Considering that Bullet was relatively the worst performing workload in the whole test suite for Raven, it is rather safe to say that the hit from the smaller L3 cache is extremely minor in general.

The difference between the Vega 8 (8CU/2RB) iGPU and Vega 11 (11CU/2RB) iGPU at the same frequency is extremely minor, usually around 8-11% depending on the memory frequency. At stock Vega 8 operates at 1100MHz engine clock and Vega 11 at 1240MHz (1251MHz nominal) engine clock. The typical overclock for both of the variants is >= 1600MHz at 1.200V SoC voltage. Due to the present memory bandwidth limitation, both of them will perform almost the same when they are overclocked close or to the typical maximum frequency.

One major thing to consider prior overclocking the iGPU on Raven APUs is the power consumption. Most of the mainstream AM4 motherboards have a 2 phase VRM for the VDDCR_SoC voltage rail (in varying quality and with varying cooling as well), which on Raven not only supplies the SoC portion of the chip but the GPU cores as well. At stock the peak power consumption of Vega 11 is around 36W. When overclocked to the typical 1600MHz engine frequency, the power consumption will raise to 55-60W. While 60W doesn't sound too high, it is more than plenty for the average 2 phase VRM (around 25A per phase).

Just like Zeppelin, Raven also features the so called "OC-Mode". On Raven there are two separate triggers to activate the “OC-Mode”: by increasing the CPU frequency or by increasing the iGPU engine frequency. Triggering either one will get rid all of the limiters (power, current, utilization) and voltage controllers, the same way as it did on Zeppelin. The only difference is that by triggering just iGPU “OC-Mode”, the Turbo / XFR features of the CPU will not be lost like they were on Zeppelin. However at least for the time being, it is not advised to only trigger the iGPU “OC-Mode”: Activating either of the “OC-Modes” will disable all of the voltage controllers, meaning that when the Turbo / XFR will still remain active the CPU voltage will raise to extremely high levels. When the CPU “OC-Mode” is activated Turbo and XFR will be disabled as well, just like on Zeppelin and the CPU voltage will remain at reasonably sane levels due to the slightly lower resulting frequencies.

Activating either of the “OC-Modes” will also immediately disable the dLDO for the GPU cores. At stock the iGPU dLDO feeds on the VDDCR_SoC voltage rail and the typical voltage drop on the regulator is around 250mV. Once the “OC-Mode” is activated the GPU dLDO is placed in a bypass mode, meaning the GPU cores will then receive the source voltage directly without any further dropouts.

The memory controller on Raven clearly contains some changes in comparison to Zeppelin, however the said changes unfortunately appear to be rather minor and quite possibly affect more the firmwares of the controller than the actual hardware IP itself. On average the memory latency has decreased by ~3% at the same settings, but the bandwidth seems to have regressed slightly at the same time. Also, the highest achievable memory frequency seems to be exactly the same as on Zeppelin, 3400 - 3533MHz depending on the silicon quality, the motherboard and the DRAM modules used. Fortunately, at least the memory training speed and reliability has been vastly improved.

Similar to Zeppelin, the frequency headroom for the CPU cores themselves is very slim over the stock frequencies. The typical, highest practical CPU frequency will be around 3.85 - 3.95GHz depending on the silicon quality.

Higher than the mentioned frequencies might be possible, however achieving them will require the voltage to be raised to a point where the power efficiency is long gone and the life time of the silicon is reduced. At frequencies beyond the inflation point (3.9GHz in the chart) the cost of the last 100MHz in frequency can easily be > 25% increase in the power consumption.

With the tested samples 4.1GHz could not be achieved even at 1.550V despite 4.0GHz was deemed stable at 1.375V, which is already high but still well in the realms of sustainable.

With Raven there is also another aspect, which is not present on Zeppelin: Unlike Zeppelin, Raven uses conventional TIM (instead of indium sTIM) between the core and the heatspreader. The conventional TIM used on Raven isn’t the only factor which affects it’s thermals either. Due to the extreme thinness of the Raven die, the heatspreader used for Raven AM4 APUs has been redesigned. Normally the contact surface inside the heatspeader is perfectly flat. The heatspreaders used on Raven have a “hump” inside them, which allows the heatspreader to make contact with the die itself. Without the “hump” the heatspreader would only make contact with the SMD components located around the die, which are standing taller than the die itself. The “hump” adds an extra 0.5mm to the heatspreader thickness and therefore increases the thermal resistance of the heatspreader as well.

Despite the Raven's slightly larger die size, the temperatures are still significantly higher at the same power dissipation and cooling. Even at a modest 65W power dissipation the CPU cores can reach excess of 70°C temperatures.

An aftermarket cooler is definitely recommended at least for the 2400G, especially if there is any plans to overclock the chip. 2400G at the stock configuration is already somewhat bound by the default 65W power limit and the chip can easily dissipate up to 120W of heat when it is overclocked to the typical maximum figures.



Some ballpark 3D performance figures, based on my own testing: RX 550 is around 22% faster and the RX 560 around 68% faster than a stock 2400G APU.
When the 2400G APU is overclocked to the typical maximum figures (1600MHz engine and 3400MHz DRAM) it’s performance is almost identical to a stock RX 550.

- 2400G at stock: 1240MHz engine, 2933MHz DRAM (3236 in 3DMark Fire Strike)
- 2400G at a typical max OC: 1600MHz engine, 3400MHz DRAM (3960 in 3DMark Fire Strike)
- RX 550 at stock: 1210MHz engine, 7000MHz (QDR) DRAM (3955 in 3DMark Fire Strike)
- RX 560 at stock: 1210MHz engine, 7000MHz (QDR) DRAM (5430 in 3DMark Fire Strike)

I don't know much about these, however if I remember correctly, the old ones could be paired with an independent GPU and utilise both, is this still the case?

Nope,AFAIK.

 

[jigger]

DX12 allows for multiple GPU's to be used and IIRC you can run hybrid configurations in crossfire with DX11.

 

[Chrisc]

Nope,AFAIK.

Would be interesting if they could.

AMD is using paste for these cheap CPUs

I think that's fair enough, it's not aimed at enthusiast markets, instead lands in the budget concious range.

If someone really wanted to they could still spend more to delid and put in metal compound.

 

[Beren]

I am going to pick one of these up tomorrow and will post some thoughts - it will be my first build for a small eternity... I have never done an install onto a clean SSD from a USB, so it is going to be an interesting experience. I am not too bothered about overclocking the CPU, the reviews seem to suggest it is already pretty finely tuned, but I will be tweaking the memory and GPU as much as possible to see if there is some extra I can squeeze out there.
I am not sure if it is worth a new thread or if we can keep it all here - but it would be awesome if as people put systems together from the forums if you could share the settings that work best for you and how you got there. An OCUK review by the forum, for the Forum.

Have Gamers Nexus fallen out with AMD? in the vid they just released Steve stated they had just bought these new APU's? where as other reviewers received them from AMD didn't they?

Depends how good the TIM is. If it's like Intel's patented 20-30 °C Hotter™ solution then it's crap. If it's not too different to solder then it's maybe acceptable for certain kinds of chips. From what I've seen, stock temperatures are great but overclocking the GPU is what hugely raises the temperature on these. Considering the relative lack of improvement from doing that, I can't see delidding being worth it for many people at all.

I notice PcPer's new disclosure info box on their reviews, which shows they got their chips on loan from AMD.

 

[Emlyn_Dewar]

If I can find some a reasonable deal on a 16gb cheap AND fast DDR4 kit, the 2400g is pretty much exactly what I want to replace the NUC.

It's a pretty big "if" though.

I wonder if its just because of him being so vocally against unboxing videos. Just guessing, but it may be that they sent the sample boxes with instructions that they had to do an unboxing video and he just refused.

But then again from stories I've heard AMD and others sales groups can be a bit hit and miss with seeding sample products, so could have been something as simple as an oversight on their part. Seems that some outlets are on some lists but not others and it doesn't always make sense as to which.

As an example I think Ed from techsource didn't get threadripper from AMD despite pestering them about it, but then did get threadripper samples from a Motherboard manufacturer, (MSI I think, could be miss-remembering)

 

[DragonQ]

I seem to remember at least one reviewer getting Threadripper and Vega within a week of each other (maybe even the same weekend) so yeah, AMD have been a bit rubbish and getting parts ready in time for release-day reviews.

Gamers Nexus Don't do Unboxings as He Stated so did not get a Press Kit.

We don't like unboxing fancy reviewer kits because they are a blatant play at influence and marketing, and provide no end value to the customer, as it cannot be purchased.

I'm quite tempted by one of these as a project. Price of DDR4 is putting me off though. 8GB isn't going to be enough once you've dedicated RAM to the graphics, and ~£200 for 16GB of fast DDR4 is bordering on obscene.

16GB kit of DDR3 was £38 last time I bought about a year ago... put 48GB in an ESXi X58 box for under £120...

It will be. People worry too much!!

I have another older generation A6 3670K based system,and it is fine for normal stuff with 8GB of system RAM.
