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 ESTStock Comparison: Real World
For our stock performance comparison, we take our four CPUs at their off-the-shelf frequency and also add in benchmark results from previous reviews for processors that are at a similar price. In the case of the Carrizo core based Athlon X4 845, which had an original MSRP of $70, this means that Intel’s dual core Pentium G3258 at $72 is the main competition. The Pentium comes with integrated graphics and a higher per-clock performance, however the Athlon has four threads to play with, which is two more than the Pentium, meaning the initial examination is a back and forth between the two.
Dolphin Benchmark: link
Many emulators are often bound by single thread CPU performance, and general reports tended to suggest that Haswell provided a significant boost to emulator performance. This benchmark runs a Wii program that raytraces a complex 3D scene inside the Dolphin Wii emulator. Performance on this benchmark is a good proxy of the speed of Dolphin CPU emulation, which is an intensive single core task using most aspects of a CPU. Results are given in minutes, where the Wii itself scores 17.53 minutes.
Dolphin historically favors Intel, and all three of our comparison points beat all the AMD processors here. The Athlon X4 845 holds the top spot for the AMD parts however.
WinRAR 5.0.1: link
Our WinRAR test from 2013 is updated to the latest version of WinRAR at the start of 2014. We compress a set of 2867 files across 320 folders totaling 1.52 GB in size – 95% of these files are small typical website files, and the rest (90% of the size) are small 30 second 720p videos.
As stated earlier in the review, the X4 845's performance is below that of the other Athlon parts due to the 2MB of L2 cache. It still stays within reasonable striking distance of the Pentium here though.
3D Particle Movement v2
The second version of this benchmark is similar to the first, however it has been re-written in VS2012 with one major difference: the code has been written to address the issue of false sharing. If data required by multiple threads, say four, is in the same cache line, the software cannot read the cache line once and split the data to each thread - instead it will read four times in a serial fashion. The new software splits the data to new cache lines so reads can be parallelized and stalls minimized. As v2 is fairly new, we are still gathering data and results are currently limited.
As 3DPMv2 is still new, we don't have G3258 results at this time, but we do have i3-6100TE results. Carrizo has an architectural advantage over other AMD microarchitectures, but the speed of the 760K means that it catches up. Both parts are ahead of the Core i3.
Web Benchmarks
On the lower end processors, general usability is a big factor of experience, especially as we move into the HTML5 era of web browsing.
Google Octane v2
Both AMD and Intel get similar scores in Octane.

Yeah lets celebrate another year of 10 or so of AMD's paper launches of incredible CPUs. Bulldozer was awesome dude!Dr. Swag - Thursday, July 14, 2016 - link
Yes, the review is finally here! Yes!nandnandnand - Thursday, July 14, 2016 - link
A review for a chip nobody should buy, because it's much worse than Zen will be.Laxaa - Thursday, July 14, 2016 - link
I wish there was a AM3+ version of Zen for us stuck on that platform. I'm not that interessted in getting a new motherboard(perhaps I should have stuck with Intel instead)Peichen - Thursday, July 14, 2016 - link
You should have stuck with Intel. I buy into AMD's upgrade CPU, motherboard at different time scheme and is now stuck with a hot old CPU and a quite new motherboard with unreliable RAID controller. Junk the whole system means I toss out a 1.5 years old motherboard. Upgrade the CPU means not much performance increase and when the board's RAID fail I will have to buy AMD again so I won't throw out a new CPU.I wish I pay slightly more for an i3 or i5 and have a reliable media/light-gaming system for 6 years without all the hassle.

well.. then you'd have been stuck with a socket 1156 cpu and no board to go with it.. Intel's gone thru what.. 5 socket changes during the last 6-7 years.. There's something to be said for throwing a 2009 cpu into a 2016 board, and it's easy enough to (at some point..) change over to one of their newer processors in that lineup.It's also a hit/miss on any hardware. While some go the distance lasting a long time .. other's fail and it's not exclusive to either platform. I use processors from both camps. +/- for both. Just depends what your using your system for and what your expecting to get out of it.

I don't know why you're whining about a 1.5 year old mainboard. Typically, your NORMAL computer enthusiast is upgrading everything every 2 to 3 years. You have the same issues with Intel, platform changes occur every 1.5 years, and you're stuck with your "old, hot" processor. Wake up and embrace the technological advancement in front of you...Nagorak - Monday, July 18, 2016 - link
What advancement?artk2219 - Wednesday, July 20, 2016 - link
Ding ding ding, we have the real question. Sure skylake is faster than sandy bridge, but compared to the advancement that 4 years used to make in chip tech, its nothing. An average of 25% IPC increase, most of which you can get back by bumping the clocks 30%, which most sandy bridge chips would do easily. Granted with skylake chip is more efficient, with more features, and better a igp, and blah blah blah. But honestly, for most things you would never notice, and dont even get me started on how pointless DDR4 is currently. But even that atleast will mature with time, unfortunately I'm sure you'll need another new socket to really realize its benefits.http://www.anandtech.com/show/9483/intel-skylake-r...
