Competition is a Great Thing

While doing some testing with the AMD Athlon 5350 Kabini APU to determine it's flexibility as a low cost gaming platform, we decided to run a handful of tests to measure something else that is getting a lot of attention right now: AMD Mantle and NVIDIA's 337.50 driver.

Earlier this week I posted a story that looked at performance scaling of NVIDIA's new 337.50 beta driver compared to the previous 335.23 WHQL. The goal was to assess the DX11 efficiency improvements that the company stated it had been working on and implemented into this latest beta driver offering. In the end, we found some instances where games scaled by as much as 35% and 26% but other cases where there was little to no gain with the new driver. We looked at both single GPU and multi-GPU scenarios on mostly high end CPU hardware though.

Earlier in April I posted an article looking at Mantle, AMD's answer to a lower level API that is unique to its ecosystem, and how it scaled on various pieces of hardware on Battlefield 4. This was the first major game to implement Mantle and it remains the biggest name in the field. While we definitely saw some improvements in gaming experiences with Mantle there was work to be done when it comes to multi-GPU scaling and frame pacing. 

Both parties in this debate were showing promise but obviously both were far from perfect.

While we were benchmarking the new AMD Athlon 5350 Kabini based APU, an incredibly low cost processor that Josh reviewed in April, it made sense to test out both Mantle and NVIDIA's 337.50 driver in an interesting side by side.

A popular question that has arisen from the release of the four new low cost Kabini processors has been their effectiveness in powering a Steam Machine. Phoronix have just finished testing the new Athlon and Sempron chips, paired with several laptop IGPs using Catalyst Linux driver fglrx 13.35.5/OpenGL 4.3.12798 on Ubuntu 14.04.  They tested Counter-Strike: Source, Half-Life 2: Lost Coast, and Portal at a variety of resolutions to see just how much performance these chips offer.  None of the chips could offer acceptable performance at 1080p and only Portal was delivered at 60fps assuming you used 1024x768.  They will be following this review with another that will pair discreet GPUs with Kabini which should increase gaming capabilities greatly.

"Earlier today the latest installment of our extensive Linux testing of AMD's new Athlon AM1 APUs were shared in the form of RadeonSI vs. Gallium3D benchmarks of the Radeon R3 Graphics found with these new entry-level APUs. Not included with that open-source vs. closed-source driver testing was any Source Engine / Steam Linux game testing due to an XCB DRI3 issue, but this article is devoted to looking at the Catalyst performance for the Sempron 2650, Sempron 3850, Athlon 5150, and Athlon 5350 to see whether any of these APUs can make the cut for a budget Steam Machine."

An easy way to trim the cost of a lower end system is to skip Windows and install Linux, along with picking a less expensive AMD chip to power your system.  AMD has recently gifted us with new Kabini based Sempron and Athlon chips, the most expensive of which is available for less that $70.  For testing Phoronix used Ubuntu 14.04, the 3.14 kernel and Mesa 10.2 along with the Radeon 7.3.99 driver.  You will be glad to know that there were no compatibility problems with Linux whatsoever, all CPUs performed more or less as expected as you can see for yourself in the full review.

"It's been a busy past few days since AMD launched their "AM1" Socketed Kabini APUs. After the initial Athlon 5350 Linux review on launch-day, I did some tests involving a faster kernel and newer Mesa code along with some reference DDR3 memory scaling benchmarks for these APUs with Jaguar processor cores. Since then the Athlon 5150 and Sempron 3850/2650 APUs arrived."

Ultra-Speed RAM, APU-Style

In our review of the Kingston HyperX Predator 2666MHz kit, we discovered what those knowledgeable about Intel memory scaling already knew: for most applications, and specifically games, there is no significant advantage to increases in memory speed past the current 1600MHz DDR3 standard.  But this was only half of the story. What about memory scaling with an AMD processor, and specifically an APU? To find out, we put AMD’s top APU, the A10-7850K, to the test!

Ready for some APU memory testing!

The APU

AMD has created a compelling option with their APU lineup, and the inclusion of powerful integrated graphics allows for interesting build options with lower power and space requirements, and even make building tiny mini-ITX systems for gaming realistic. It’s this graphical prowess compared to any other onboard solution that creates an interesting value proposition for any gamer looking at a new low-cost build. The newest Kaveri APU’s are getting a lot of attention and they beg the question, is a discrete graphics card really needed for gaming at reasonable settings?

AMD Kabini Chips Now Available At Retail

Subject: Processors | April 10, 2014 - 01:38 PM |
Tagged: sempron, Kabini, Athlon 5350, athlon, amd, AM1

AMD has officially announced its socketed Kabini chips and the AM1 platform. Information on the chips and motherboards have been slowly trickling out since CES, but now they are finally official and available for purchase at retail.

Specifically, AMD has launched four desktop Kabini processors under the Athlon and Sempron brands. In addition ASRock, ASUS, Biostar, ECS, Gigabyte, and MSI all have AM1 platform motherboards ready to accept the new AMD chips. The motherboards come in mini ITX and micro ATX form factors.

The AMD Athlon 5350 SoC Installed in the ASUS AM1I-A motherboard which was used in our full Kabini review.

All four of the AMD chips have 25W TDPs and integrated GPUs with 128 stream processors. The Kabini chips support four PCI-E 2.0 lanes, two SATA III 6 Gbps ports, two USB 3.0 ports, and eight USB 2.0 ports. Motherboard permitting, the Kabini GPU supports up to three display outputs (HDMI, DisplayPort, and VGA). The chips differ by CPU and GPU clockspeeds, core count, and DDR3 memory frequency support. On the low end, the $34 (MSRP) Sempron 2650 is a dual core part clocked at 1.45 GHz with a GPU clocked that 400 MHz that supports a maximum memory clockspeed of 1333 MHz. The top-end Athlon 5350 is a quad core processor clocked at 2.05 GHz with a GPU clocked at 600 MHz and supports DDR3 1600 MHz. This chips has a $59 MSRP. The desktop chips are similar to their mobile counterparts, with slight differences in clockspeed and (of course) price and the socketed implementation.

Processor TDP CPU L2 Cache GPU Maximum Memory Speed Price
Athlon 5350 25W 4 cores @ 2.05 GHz 2MB 128 SPs @ 600 MHz 1600 MHz $59
Athlon 5150 25W 4 cores @ 1.6 GHz 2MB 128 SPs @ 600 MHz 1600 MHz $49
Sempron 3850 25W 4 cores @ 1.3 GHz 2MB 128 SPs @ 450 MHz 1600 MHz $39
Sempron 2650 25W 2 cores @ 1.45 GHz 1MB 128 SPs @ 400 MHz 1333 MHz $34

The motherboards for the new Kabini processors will come in mini ITX and micro ATX. We previously covered AM1 platform boards from ASRock, Biostar, and MSI. In general, the boards offer up most of the standard IO and other functionality that enthusiasts are used to from existing AMD motherboards including multiple display outputs, networking, audio, and a plethora of USB ports on the rear IO panel and SATA ports, PCI Express slot(s), and two DDR3 DIMM slots internally. Interestingly, the boards are fairly bare and free from chipsets because the IO is included in the processor itself. This enables motherboards that are notably cheaper than, say, FM2+ and AM3 boards.

When AMD first launched the AM1 platform, the company stated that a combination of a Kabini chip and FS1b-socketed motherboard would add up to about $60. Now that the platform is official, retail prices are starting to pop up. With the Kabini processors and motherboards each ranging from around $30 to $60, AMD has technically hit that mark. Adding a hard drive, RAM, and enclosure will get you a baisc and complete system for less than $150.

AMD's Kabini chips are set to compete against Intel's Bay Trail-D processor which comes pre-soldered onto motherboards. The AM1 platform does look to be the slightly cheaper option that also gives users the choice of motherboard and the possibility of upgrading to soecketed Beema (Kabini's successor) SoCs.

AMD Brings Kabini to the Desktop

Perhaps we are performing a study of opposites?  Yesterday Ryan posted his R9 295X2 review, which covers the 500 watt, dual GPU monster that will be retailing for $1499.  A card that is meant for only the extreme enthusiast who has plenty of room in their case, plenty of knowledge about their power supply, and plenty of electricity and air conditioning to keep this monster at bay.  The product that I am reviewing could not be any more different.  Inexpensive, cool running, power efficient, and can be fit pretty much anywhere.  These products can almost be viewed as polar opposites.

am1_APU_Comp.jpg

The interesting thing of course is that it shows how flexible AMD’s GCN architecture is.  GCN can efficiently and effectively power the highest performing product in AMD’s graphics portfolio, as well as their lowest power offerings in the APU market.  The performance scales very linearly when it comes to adding in more GCN compute cores.

The product that I am of course referring to are the latest Athlon and Sempron APUs that are based on the Kabini architecture which fuses Jaguar x86 cores with GCN compute cores.  These APUs were announced last month, but we did not have the chance at the time to test them.  Since then these products have popped up in a couple of places around the world, but this is the first time that reviewers have officially received product from AMD and their partners.
