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).

Fantastic work, Ian. Now if AMD put half as much work into their uArchs as you did into reviewing them, we might finally get somewhere =PGeranium - Thursday, July 14, 2016 - link
Ian,Exynos 7420 and Apple A9 is built on Samsang's 14nm LPE. Exynos 8890 and Snapdragon 820 is built on 14nm LPP.

AMD CPU R&D has been outsourced pretty much close to an 1 year ago. Even Jim Keller left before anything(silicon) was remotely close to be released. AMD has submitted on the CPU front, and now with the another failure from the RX 480 power fiasco it seems in the GPU segment too. ZEN is just a myth for the small minded amoebas. The closest they can come to is Haswell, even in some benchmarks they will be far behind.Intel has reported times in many improvement over the 4/5y spam CPU's. AMD can barely get 30% and in some synthetic benchmarks they are below something was produced/developed half a decade ago.

You have sources for your ludicrous claims?wumpus - Friday, July 15, 2016 - link
Zen tapped out. Thus the drawdown. But if you think Zen will compare as well to Intel silicon as the 480 does to the 1060, remember that Intel is still hand-laying out the transistors and AMD is using autorouters.Hopefully AMD will at least be able to get back to producing "the cheap stuff', but that is their best hope. They've pretty much surrendered.

Great article, overall! I am glad to see someone finally review the product.I was hoping, however, that you would come across this strange "throttling" issue that this CPU seems to have while playing certain games (not all games, just certain ones). Some people have started threads on Tom's Hardware, and I started one on AMD's own forums:

Yeesh, the barest overclock physically degrades the processor? This likely means it's degrading at stock as they've pushed a 35W part to 65W and beyond.Sherlock - Thursday, July 14, 2016 - link
/rantWho's your web-designer Anandtech - seriously - I see a big banner at the top & two big ads on the left & right of the page. I am so pissed by the design - I actually calculated the pixel count - only 24% of the screen is dedicated to content - excluding the large Anandtech logo & the menu bars - 10% for the screen is content - please don't kill the site with such crap

Also - "For clarity, hand was from AMD but not Lisa Su's" :)

A narrow column is more readable. Who cares what's on the sides?The_Assimilator - Friday, July 15, 2016 - link
