AMD Carrizo Part 2: A Generational Deep Dive into the Athlon X4 845 at $70
by Ian Cutress on July 14, 2016 9:00 AM ESTMiddle-Earth: Shadows of Mordor at 3 GHz
The final title in our testing is another battle of system performance with the open world action-adventure title, Shadows of Mordor. Produced by Monolith using the LithTech Jupiter EX engine and numerous detail add-ons, SoM goes for detail and complexity to a large extent, despite having to be cut down from the original plans. The main story itself was written by the same writer as Red Dead Redemption, and it received Zero Punctuation’s Game of The Year in 2014.
For testing purposes, SoM gives a dynamic screen resolution setting, allowing us to render at high resolutions that are then scaled down to the monitor. As a result, we get several tests using the in-game benchmark, taking results as the average and minimum frame rates.
For this test we used the following settings with our graphics cards:
| Shadow of Mordor Settings | |||
| Resolution | Quality | ||
| Low GPU | Integrated Graphics | 1280x720 | Low |
| ASUS R7 240 1GB DDR3 | |||
| Medium GPU | MSI GTX 770 Lightning 2GB | 1920x1080 | Ultra |
| MSI R9 285 Gaming 2G | |||
| High GPU | ASUS GTX 980 Strix 4GB | 1920x1080 3840x2160 |
Ultra Ultra |
| MSI R9 290X Gaming 4G | |||
Carrizo takes miniture solace here in that it beats the Kaveri CPU at 4K with a GTX 980, albeit within the margin of error. SoM typically performs very similar no matter the processor, especially on NVIDIA cards. We haven't included the R9 285 results, as there seems to have been a recent update pushing values 30% higher than expected for the Kaveri on this GPU, and given the results trend it would seem to be more than simply L2 or PCIe lane difference, especially to the Trinity/Richland parts.

I'm predicting Bristol Ridge will be just as bad a failure as Carrizo. I.e. the few design wins will only have single DIMM memory and be universally unavailable, buried somewhere in a dark corner of the OEM's website. It's a pity, because both SoCs are very good in their own right.nandnandnand - Thursday, July 14, 2016 - link
If it's not Zen, it can be thrown straight in the garbage.Samus - Friday, July 15, 2016 - link
I still rock a few Kaveri desktops and they are incredibly powerful for the price. The 860K is half the cost of a comparable Intel chip, which supporting faster memory and a lower cost platform.Carizo on the desktop is an anomaly. I'd like to see what it could do with 4MB cache (would require an entirely new die)

They were nice in 2014.We should have a nice 20nm 768SP APU in 2015 with a full L2 cache Excavator and fully mature 896SP 20nm early this year.
Remember the A8 3870K? That APU was a damn monster only hold back from being godly cause of their sub 3Ghz cpu speed, what we had after?
400SP VLIW5 2011 --> 384 VLIW4 2012 --> 384VLIW4 2013 --> 512SP GCN 2015 --> 512SP GCN 2016
Intel improved way faster (non "e" + edram igp's are near A8 level from being utter trash when the A8 3850 was release).

yes being able to thrown in a extra billion transistors compared to AMD (1.7 vs 0.75 billion transistors for a quad core with GPU) because of 14nm really does help intel along a lot.but as nobody has been able to make a 20nm class process for anything but flash and ram besides intel, AMD's hands were tied. there is nothing AMD could have done to change that.

Formula for failure: FM2 socket (with limited CPU upgradeability), only PCI Express x8 lanes available (which can bottleneck GPUs), and only "4 cores" (which performs more like 2C/4T Core i3 processor).neblogai - Friday, July 15, 2016 - link
Bristol Ridge is not FM2; PCI-E x8 can not bottleneck midrange GPUs; ultra low power mobile APU also sold as desktop chip is not a failure, just additional revenueBlueBlazer - Friday, July 15, 2016 - link
The results in the article shows otherwise, where AMD's Bristol Ridge was slower in most gaming tests, despite having better performance in some applications. Both FM2 and FM2+ are still the same (legacy) socket. AMD will be probably selling these chips at a loss. Note that these are the same (large) dies as Carrizo chips, and at 250mm^2 coupled with low prices typically meant razor thin margins or none at all.silverblue - Friday, July 15, 2016 - link
That L2 cache is probably making more difference than you realise.evolucion8 - Saturday, July 16, 2016 - link
The PCI-E is busted, even at PCI E 2.0 @ 4X, it barely makes a difference on the Fury X and the GTX 980 Ti.
