AMD Carrizo Part 2: A Generational Deep Dive into the Athlon X4 845 at $70

The highly anticipated iteration of the Grand Theft Auto franchise finally hit the shelves on April 14th 2015, with both AMD and NVIDIA in tow to help optimize the title. GTA doesn’t provide graphical presets, but opens up the options to users and extends the boundaries by pushing even the hardest systems to the limit using Rockstar’s Advanced Game Engine. Whether the user is flying high in the mountains with long draw distances or dealing with assorted trash in the city, when cranked up to maximum it creates stunning visuals but hard work for both the CPU and the GPU.
For our test we have scripted a version of the in-game benchmark, relying only on the final part which combines a flight scene along with an in-city drive-by followed by a tanker explosion. We record both the average frame rate and the percentage of frames under 60 FPS (16.6ms).
For this test we used the following settings with our graphics cards:
| Grand Theft Auto Settings | |||
| Resolution | Quality | ||
| Low GPU | Integrated Graphics | 1280x720 | Lowest |
| ASUS R7 240 1GB DDR3 | |||
| Medium GPU | MSI GTX 770 Lightning 2GB | 1920x1080 | Very High |
| MSI R9 285 Gaming 2G | |||
| High GPU | ASUS GTX 980 Strix 4GB | 1920x1080 | Very High |
| MSI R9 290X Gaming 4G | |||
If we look purely at the average frame rates first, the same pattern as the other tests shows here. Carrizo sits between Kaveri and Trinity, anywhere from 3-7% behind Kaveri.

If we compare the time spent under 60 FPS, again Kaveri takes the lead over Carrizo. The low end GPU is interesting, showing a good trend towards the newer microarchitectures, but still in favor of Kaveri with 4 MB of L2 cache over Carrizo with 2 MB of L2.

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.
