Who Controls the User Experience? AMD’s Carrizo Thoroughly Tested
by Ian Cutress on February 4, 2016 8:00 AM ESTBenchmark Results: CPU Short Form
Here are our results from our CPU tests. A reminder of our systems:
| System Overview | |||||
| µArch | APU | Base / Turbo MHz | Memory | Channel | |
| HP Elitebook 745 G2 | Kaveri | A10 PRO-7350B (19W) | 2100 / 3300 | 8 GB | Dual |
| HP Elitebook 745 G3 | Carrizo | PRO A12-8800B (15W) | 2100 / 3400 | 4 GB | Single |
| Toshiba Satellite E45DW-C4210 |
Carrizo | FX-8800P (15W) | 2100 / 3400 | 8 GB | Single |
| HP Pavilion 17z-g100 |
Carrizo | A10-8700P (15W) | 1800 / 3200 | 8 GB | Single |
| Lenovo Y700 | Carrizo | FX-8800P (35W) | 2100 / 3400 | 16 GB | Single |
Three Dimensional Particle Movement (3DPM)
3DPM is a self-penned benchmark, derived from my academic research years looking at particle movement parallelism. The coding for this tool was rough, but emulates the real world in being non-CompSci trained code for a scientific endeavor. The code is unoptimized, but the test uses OpenMP to move particles around a field using one of six 3D movement algorithms in turn, each of which is found in the academic literature. This test is performed in single thread and multithreaded workloads, and uses purely floating point numbers. The code was written in Visual Studio 2008 in Release mode with all optimizations (including fast math and –Ox) enabled. We take the average of six runs in each instance.
In the single threaded mode, the 35W part is able to boost to a higher frequency, giving it the lead. The interesting element here is the mix of 15W and 19W results, putting the Pavilion with the A10-8700P at the bottom. This comes through in the frequency charts, where the Kaveri was able to boost above 3000 MHz often:
For multithreaded:
The processors line up more as expected, with the 8800P still taking the top spot with Carrizo’s architecture resources showing the ability to scale better.
WinRAR 5.01
WinRAR is a compression tool to reduce file size at the expense of CPU cycles. We use the version that has been a stable part of our benchmark database through 2015, and run the default settings on a 1.52GB directory containing over 2800 files representing a small website with around thirty half-minute videos. We take the average of several runs in this instance.
WinRAR is a benchmark which loves DRAM speed, hence why the dual channel Kaveri system wins despite the increased horse power and thermal benefits of the Lenovo Y700. Unfortunately, the single channel design methodology permeates through the OEMs because of the factor of price and upgradability – if a machine is sold with only one module, it can be upgraded later. The other element is that the Y700 design also caters for Carrizo-L as pin compatible, so despite having two modules in there the system will always be limited to single channel. This is, perhaps, a grave error with any situation that is memory limited.
POV-Ray 3.7 beta
POV-Ray is a common ray-tracing tool used to generate realistic looking scenes. We've used POV-Ray in its various guises over the years as a good benchmark for performance, as well as a tool on the march to ray-tracing limited immersive environments. We use the built-in multithreaded benchmark.
For whatever reason, our script failed to record the score when it came to the Kaveri system and we only realized after the systems were returned. Nonetheless, the capabilities of the other systems shine through, showing that the A10-8700P can seem to have a big frequency discrepancy against the FX-8800P models. In actual fact this can be attributed to the temperature limitations on the Pavilion:
The full threaded nature of POV-Ray means that we’re on the limits of the A10 APU already, but when the system hits 55C or so, it clocks back to 2100 MHz to save a few extra degrees.
If we compare that to the Toshiba:
The Toshiba system also hits a temperature limit, but the barrier is way up at 70C, causing the system to knock back to 64C. The CPU frequency difference between the two does not look that different despite the +25% score in favor of the Toshiba, making it slightly deceptive.
HandBrake
HandBrake is a freeware video conversion tool. We use the tool in to process two different videos - first a 'low quality' two hour video at 640x388 resolution to x264, then a 'high quality' ten minute video at 4320x3840. The low quality video scales at lower performance hardware, whereas the buffers required for high-quality can stretch even the biggest processors. At current, this is a CPU only test.
Unfortunately HandBrake also had issues on a couple of systems – the Lenovo and the Toshiba. All the HP systems gave results, where the HP Pavilion came out on top:
If we compare CPU use, the HP Pavilion is much better at using all of its threads than the Elitebook 745 G3:
7-Zip
7-Zip is a freeware compression/decompression tool that is widely deployed across the world. We run the included benchmark tool using a 50MB library and take the average of a set of fixed-time results.
Despite being a purely in-memory benchmark, the G2 shows some inefficiency compared to the Carrizo systems. The slight discrepancy between the 8800 and 8700 shows again, and the Y700 can stretch its legs. Interestingly, the Y700 was able to keep its full CPU frequency on all the time:
Despite the temperature of the CPU moving between 55C and 65C, the system never once reduced its frequency.

no A12 core parts for the test? I can't find the A10 part on the HP websiote, only A8 & A12UtilityMax - Wednesday, February 10, 2016 - link
After a decade of hype since the ATI acquisition, nothing has changed. AMD has a massive OEM problem. Moreover, laptops have been outselling desktops for like a decade, yet AMD if you look at the history of AMD, it's hard to believe they ever really cared about portables. The Kaveri parts didn't even show up, while the Carrizo notebooks are already botched technology as explained in the article..gserli - Thursday, February 11, 2016 - link
I have to say that the $400 to $700 notebooks on sale are garbage.The IGPs are not strong enough for casual gaming like LOL and CS GO.
Crappy 5400RPM harddisk will make you want to throw the machine out of the window.
If you really need that little bit more performance.
Pay few hundred more. Or you can get a notebook that will hurt your arm if you carry it with one hand.
AMD needs to be more aggressive. Talk to the OEMs and give them better offer.
Convince them build a $700 notebook with 13 Inch 1080p IPS touch screen, 256GB SSD, 8GB RAM, A8 or A6 APU and below 1.5KG.
A lower end $600 one would work with 1366*768 IPS touch screen, 128GB SSD, 4GB RAM and A6 APU, below 1.5KG.
My $640 Asus TP300L is absolutely bullshit! I thought a mobile i5 would be enough for my daily use since I had a i5 desktop and was really satisfied with it.
CPU performance is not a issue nowadays. The IGP is slow, but I didn't expect it to be fast(Although the one on desktop is way more powerful).
The biggest problem is the GOD DAMN 5400RPM HARD DISK.
Not only did it affect the boot up speed. Every action I performed is awfully slow when there are some OS things running in background.
Only if I wait for 5 or 10 minutes after boot-up, then I can use it normally.
Please, kill all the 5400RPM Hard disk. They should not be in 2016.

That's what I find so hilarious about all the Y700 6700hq lovers out there - all the CPU power in the world is relegated to potato status outside of b.s. benchmarks with that 5400rpm HDD. Save money with the FX8800p Y700 and buy an $80 250GB Samsung 850 Evo to slap in it...wow&wow - Thursday, February 11, 2016 - link
Will it be more appropriate to have "Additional" (Why not Update?) in the beginning, particularly the misleading pre-production stuff? Thanks for the article.farmergann - Thursday, February 11, 2016 - link
LOL, because the entire point of this article would be nullified. They didn't even bother comparing the FX8800p Y700 with the intels head to head outside of some DX9 garbage. Pitiful anandtech shills are pitiful. How many times did they mention Freesync? Yeah...silverblue - Friday, February 12, 2016 - link
To be fair, is there a point?xrror - Thursday, February 11, 2016 - link
"Some companies in the past have dealt with contra-revenue, selling processors at below cost or with deals on multiple parts when purchased together. Very few companies, typically ones with large market shares in other areas, have access to this. Some members of the industry also see it as not fighting fair, compared to actually just pricing the parts lower in the first place."I had to laugh so much as this. WHO COULD IT BE? MYSTERY!
It must be... Cyrix ! no? hrm. I give up. =P

still ... there is just no saving the bulldozer architecture, no matter how much they improve or iterate it.bulldozer and amd by proxy for normal users are synonyms for "just not as good as intel" and for a little more experienced users "that processor that cheated with its core count".
the few people who actually read articles like the one above and compare performance/value represent literally no market share.
the only way out for amd at this point is to create as much boom around their zen-cores as possible, get them out asap, hitch their little start to new buzzwords like hbm, old buzzwords like rage and hope they can actually deliver the performance figures needed in the first reviews to drive a wave of positive articles through the press. only then will they be able to get back into the market. i wish them the best, a surface 5 (non pro) with a low power zen apu on hbm sounds awsome ... i'd get one of those in a heartbeat.

I own a Toshiba P50D-C-104. I read with interest this article and, albeit extremely helpful and rich of information, left some questions open, at least as far a I'm concerned.First of all, the P50D-C-104 costs <$600 and has an A10-8700P. I find this price range more relevant for home-users and, in general, for somebody interested in AMD offering.
1Kusd for a laptop with integrated GPU seems too expensive.
The P50D-C-104 has 2 DIMM slots; couldn't find for sure whether it is dual channel or not.
I am curios to know how it performs on some popular games against Intel's offering (at that price level, it would go against core i3, at best). In the page with comparison against Intel's offering there are almost only synthetic benchmarks: it would have been nice to compare on some actual games.
My point is that in the $1K range, there are many features that could add cost while not necessarily improving performance.
