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."

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.
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.
Athlon and Pentium Live On
Over the past year or so, we have taken a look at a few budget gaming builds here at PC Perspective. One of our objectives with these build guides was to show people that PC gaming can be cost competitive with console gaming, and at a much higher quality.
However, we haven't stopped pursuing our goal of the perfect inexpensive gaming PC, which is still capable of maxing out image quality settings on today's top games at 1080p.
Today we take a look at two new systems, featuring some parts which have been suggested to us after our previous articles.
|AMD System||Intel System|
|Processor||AMD Athlon X4 760K - $85||Intel Pentium G3220 - $65|
|Cores / Threads||4 / 4||2 / 2|
|Motherboard||Gigabyte F2A55M-HD2 - $60||ASUS H81M-E - $60|
|Graphics||MSI R9 270 Gaming - $180||MSI R9 270 Gaming - $180|
|System Memory||Corsair 8GB DDR3-1600 (1x8GB) - $73||Corsair 8GB DDR3-1600 (1x8GB) - $73|
|Hard Drive||Western Digital 1TB Caviar Green - $60||Western Digital 1TB Caviar Green - $60|
|Power Supply||Cooler Master GX 450W - $50||Cooler Master GX 450W - $50|
|Case||Cooler Master N200 MicroATX - $50||Cooler Master N200 MicroATX - $50|
(Editor's note: If you don't already have a copy of Windows, and don't plan on using Linux or SteamOS, you'll need an OEM copy of Windows 8.1 - currently selling for $98.)
These are low prices for a gaming computer, and feature some parts which many of you might not know a lot about. Let's take a deeper look at the two different platforms which we built upon.
First up is the AMD Athlon X4 760K. While you may not have known the Athlon brand was still being used on current parts, they represent an interesting part of the market. On the FM2 socket, the 760K is essentially a high end Richland APU, with the graphics portion of the chip disabled.
What this means is that if you are going to pair your processor with a discrete GPU anyway, you can skip paying extra for the integrated GPU.
As for the motherboard, we went for an ultra inexpensive A55 option from Gigabyte, the GA-F2A55M-HD2. This board features the A55 chipset which launched with the Llano APUs in 2011. Because of this older chipset, the board does not feature USB 3.0 or SATA 6G capability, but since we are only concerned about gaming performance here, it makes a great bare bones option.

It might not be entirely obvious to viewers, but I love old hardware. I came across a stash of old machines at my workplace that we were going to just throw away. I was able to grab a couple of pretty interesting products from years past that I wanted to share and chat about. The first of this series should be very familiar to most of you, especially those around when Ryan started his first website.
It is fun to reminisce about old hardware. The K7M is a classic.
The Asus K7M was one of the first Slot A motherboards out. It was arguably the most fully featured of the group. Its primary competition was the FIC SD-11 and the Gigabyte GA-7IXE. If you remember that monster of a board (with one very strange layout) then you most certainly have fond memories of what Asus was able to bring to the table.
The K7M was based on the AMD “Irongate” northbridge (AMD-751). This was a pretty fully featured chip at the time. It supported SDRAM up to 100 MHz and featured AGP 2X. This chip was rumored to contain IP from VIA, but it had distinctly better performance than the competing AGP 2X chipsets from VIA at the time. I distinctly remember having fewer AGP issues with these boards than products from VIA. The K7M eschewed the AMD 756 southbridge and instead used the VIA 686A controller. This was an updated (and fixed) southbridge from VIA that supported up to ATA-66 speeds and USB 1.1.
Integrated audio was still uncommon back in the day. If you thought mobo audio quality is bad now...
The K7M was a decent overclocker for the time, but little was known about the EV-6 bus and how it reacted to overclocking. Bus speeds up to 107 MHz or so were common, but anything above that got pretty flaky fast. Later BIOS revisions helped a bit, but the 751 was not going to be pushed much further. It was not until official 133 MHz support came in did we see some legroom with overclocking.
The K7M was a very solid board for being an introductory product. One thing that always amused me greatly was that Asus, Gigabyte, and other motherboard manufacturers would refuse to show Slot A boards on the floor of Comdex because they feared that Intel would come down upon them like a ton of bricks. If a person wanted to see a Slot A board, they would have to go into a back room and view it from there, but only upon request. It was not until the next year that some manufacturers cautiously showed off their AMD offerings.
Name that mini-slot above the AGP!
I ran this particular board for a while. I believe I ran the SD-11 longer. I was doing reviews all the time, so I was swapping out motherboards pretty frequently. The Asus had a luxury feel about it as compared to the FIC and Gigabyte offerings. It even had integrated audio and a game port. Few other products of the time included such a perk. AMD was on a roll with the original K7 Athlon, and Asus was one of the first partners to really produce a world class motherboard for the architecture.

NVIDIA’s new Kepler graphics cards (such as the GTX 660 we recently reviewed) will be getting most of the PC enthusiast attention today, but there is a bit of news about AMD to talk about as well.
The Trinity APU die.
Thanks to a Gigabyte motherboard compatibility list that was accidentally leaked to the internet, it was revealed that Advanced Micro Devices (AMD) would be repurposing Trinity APU dies that don’t quite make the cut due to non-operative graphics cores. Instead of simply discarding the processors, AMD is going to bin the chips into at least three CPU-only Athlon-branded processors. The Athlon X4 730, X4 740, and X4 750K are the three processors that are (now) public knowledge. All three of the CPUs have TDP ratings of 65W, and the X4 750K is even unlocked – allowing for overclocking. Further, the processors are all quad core parts with a total of 4MB of L2 cache (1MB per core).
The new Athlon-branded processors will be supported by the A75 chipset and will plug into FM2-socket equipped motherboards.
The following chart details the speeds and feeds of the Athlon processors with Trinity CPU cores.
|Athlon X4 730||2.8GHz||65W|
|Athlon X4 740||3.2GHz||65W|
|Athlon X4 750K||3.4GHz||65W|
Unfortunately, there is no word on pricing or availability. You can expect them to be significantly cheaper than the fully fledged Trinity processors to keep them price-competitive and in-line with the company's traditional CPU-only processors.
Would you consider rolling a Trinity-based Athlon in a budget build?
