The AMD A8-7650K APU Review, Also New Testing Methodology
by Ian Cutress on May 12, 2015 10:00 AM ESTAMD A8-7650K Conclusion
I've mentioned the story before, but last summer I built a system for my cousin-in-law out of spare parts. His old system, ancient and slow even by the standards when they were made, was still used for basic online browsing and school work. He had no budget, and I cobbled together an MSI motherboard, some DDR3, a mid-range Trinity APU (A8-5500), an AMD GPU and an SSD for him. Understandably he can now play CS:Go, DOTA2, Watch_Dogs and the like at semi reasonable settings in dual graphics mode, as well as watch videos without the processor grinding to a halt. He even plays GTA V at normal settings at his native resolution of 1440x900. The total system budget, if purchased new, would have been around the $300 mark, or console territory. We reused the case and power supply, and he bought a new storage drive, but for his use case it was a night and day change. Building the equivalent system on an Intel backbone would have been a stretch or it would have ended up substituting gaming performance (my cousin-in-law's priority) for other features he didn't care for.
AMD will advertise that they don't just cater to this line of updates, and that the APU line offers more than just an upgrade for entry level gamers. In the majority of our discrete gaming scenarios, this is also true. While the APUs aren't necessarily ahead in terms of absolute performance, and in some situations they are behind, but with the right combination of hardware the APU route can offer equivalent performance at a cheaper rate. This is ultimately why APUs were recommended in our two last big gaming CPU overviews for single GPU gaming, and for integrated gaming. In our new test, it was really interesting to see where the lines are drawn with different CPU and GPU combinations, both integrated and discrete from $70 to $560. One take home test result is our Grand Theft Auto benchmark nearing 60 FPS at 720p Low settings.

I confess that I do not game as much as I used to. Before AnandTech I played a couple of games in clan tournaments, and through thick and thin I did well enough on public servers for Battlefield 2142 and BC2, but clan matches were almost always duds. However, with the right hardware or the right software, I get one AAA title a year and usually do the full single player with a bit of multiplayer. That game for 2015 is Grand Theft Auto V, which I was able to benchmark for this review. On its own, an APU can handle 720p at low settings with a reasonable frame rate, meaning that when the drivers are in place, An APU in dual graphics mode running at 60 FPS with decent quality shouldn't be too hard to achieve. For 2015 and 2016, that percentage of frames over 60 FPS metric for GTA should be a holy grail for integrated graphics.
We've actually got a couple more APUs in to test in the form of the A10-7700K and the A6-7400K, which are slightly older APUs but fill in the Kaveri data points we are missing. Stay tuned for that capsule review. Rumor also has it that there will be updates to the Kaveri line soon, although we haven’t had any official details as of yet.

This comment is for Ian Cutress,First, thank you for the review, which was rich with performance figures and information. That said, something seems missing in the Conclusion. To be precise, the article doesn't really have a clear conclusion or recommendation, which is what many of us come here for.
It's nice to hear about your cousin-in-law's good experiences, but the conclusion doesn't clearly answer the key question I think many readers might have: Where does this product fit in the world of options to consider when buying a new processor? Is it a good value in its price range? Should it be ignored unless you plan to use the integrated graphics for gaming? Or does it offer enough bang-for-the-buck to be a viable alternative to Intel's options for general non-gaming usage, especially if motherboard costs are considered? Should we consider AMD again, if we are in a particular niche of price and desired features?
Basically, after all of your time with this chip and with your broader knowledge of the market offerings, what is your expert interpretation of the merits or demerits of considering this processor or its closely related AMD peers?

" Ultimately AMD likes to promote that for a similarly priced Intel+NVIDIA solution, a user can enable dual graphics with an APU+R7 discrete card for better performance."I have *long* wondered why Intel and Nvidia don't get together and figure out a way to pair up the on-board graphics power of their CPUs with a discrete Nvidia GPU. It just seems to me such a waste for those of us who build our rigs for discrete video cards and just disable the on-board graphics of the CPU. Game developers could code their games based on this as well for better performance. Right now game developer Slightly Mad Studios claims their Project Cars racing simulation draws PhysX from the CPU and not a dedicated GPU. However, I have yet to find that definitively true based on benchmarks...I see no difference in performance between moving PhysX resources to my GPUs (970 SLI) or CPU (4690K 4.7GHz) in the Nvidia control panel in that game.

Something similar to what you're describing is coming in DX12...But the main reason they haven't is because unless youre one of the few people who got an AMD APU because your total CPU+GPU budget is around 100$ it doesn't make any sense.
First if all, the performance you get from an Intel igpu in a desktop system will be minimal, compared to even a 2-300$ Nvidia card. And secondly, if you crank up the igpu on an Intel CPU, it may take away some of the CPUs performance/overhead.
If we're talking about a laptop, taking watts away from the CPU, and overall negatively impacting battery life will be even bigger drawbacks.

"But the main reason they haven't is because unless youre one of the few people who got an AMD APU because your total CPU+GPU budget is around 100$ it doesn't make any sense."Did you even read the hardware I have? Further, reading benchmarks from the built in 4600 graphics of i3/i5/i7 CPUs shows me that it is a wasted resource. And regarding impact on CPU performance, considering that higher resolutions (1440p and 4K) and higher quality/AA settings are more dependent on GPU performance than CPU performance, the theory that utilizing onboard CPU graphics with a dedicated GPU would decrease overall performance is debatable. I see little gains in my highly overclocked 4690K running at 4.7GHz and running at the stock 3.9GHz turbo frequency in most games.
All we have to go on currently is 1) Intel HD 4600 performance alone in games, and 2) CPU performance demands at higher resolutions on games with dedicated cards.

I am guessing that they didn't get together because dual-graphics is very difficult to make to work right. AMD is putting effectively the same type of GPU cores on the discrete GNUs and integrated APUs, and it still took them a while to make it work at all.V900 - Thursday, May 14, 2015 - link
I guess one thing we all learned today, besides the fact that AMDs APUs still kinda blow, is that there is a handful of people, who are devoted enough to their favorite processor manufacturer to seriously believe that:A: Intel is some kind of evil and corrupt empire ala Star Wars.
B: They're powerful enough to bribe/otherwise silence "da twooth" among all of Anandtech and most of the industry.
C: 95% of the tech press is corrupt enough to gladly do their bidding.
D: Mantle was an API hardcoded by Jesus Christ himself in assembler language. It's so powerful that if it got widespread, no one would need to buy a new CPU or GPU the rest of this decade. Which is why "they" forced

Which is why "they" forced AMD to cancel Mantle. Then Microsoft totally 110% copied it and renamed it "DX12".Obviously all of the above is 100% logical, makes total sense and is much more likely than AMD releasing shoddy CPUs the last decade, and the press acknowledging that.

AMD DOMINATION!!!!! If only the charts looked like that with discrete graphics as well....Vayra - Friday, May 15, 2015 - link
Still really can't see a scenario where the APU would be the best choice. Well, there may be one: for those with a very tight budget and wish for playing games on PC regardless. But this would mean that AMD has designed and reiterated a product that would only find its market in the least interesting group of consumers: those that want everything for nothing... Not really where you want to be.UtilityMax - Friday, May 15, 2015 - link
Well, right now arguably, if one has $500 bucks or less for a gaming PC build, it would be better to buy a Playstation 4. High end builds is where the money is in the enthusiast gaming market.
