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 ESTGRID: Autosport at 3 GHz
No graphics tests are complete without some input from Codemasters and the EGO engine, which means for this round of testing we point towards GRID: Autosport, the next iteration in the GRID and racing genre. As with our previous racing testing, each update to the engine aims to add in effects, reflections, detail and realism, with Codemasters making ‘authenticity’ a main focal point for this version.
GRID’s benchmark mode is very flexible, and as a result we created a test race using a shortened version of the Red Bull Ring with twelve cars doing two laps. The car is focus starts last and is quite fast, but usually finishes second or third. Both the average and minimum frame rates are recorded.
For this test we used the following settings with our graphics cards:
GRID: Autosport Settings | |||
Resolution | Quality | ||
Low GPU | Integrated Graphics | 1920x1080 | Medium |
ASUS R7 240 1GB DDR3 | |||
Medium GPU | MSI GTX 770 Lightning 2GB | 1920x1080 | Maximum |
MSI R9 285 Gaming 2G | |||
High GPU | ASUS GTX 980 Strix 4GB | 1920x1080 | Maximum |
MSI R9 290X Gaming 4G |
The EGO engine typically shows off any small changes in hardware configuration, which can be a good thing, and similar to the other tests the average frame rates favor Kaveri.
Minimum frame rates show a similar story. It's interesting to note that on our AMD cards, the R9 285 and R9 290X, both Carrizo and Kaveri push the minimum frame rates from below 30 to above 30, despite the fact that the AMD cards seem to have a poor showing for GRID (at least at 3 GHz).

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.
