As a follow up to our first video posted earlier in the week that looked at the A10-7850K and the GT 630 from NVIDIA in five standard games, this time we compare the A10-7850K APU against the same combination of the Intel and NVIDIA hardware in five of 2013's top free to play games.

UPDATE: I've had some questions about WHICH of the GT 630 SKUs were used in this testing.  Our GT 630 was this EVGA model that is based on 96 CUDA cores and a 128-bit DDR3 memory interface.  You can see a comparison of the three current GT 630 options on NVIDIA's website here.

A troubled launch to be sure

AMD has released some important new drivers with drastic feature additions over the past year.  Remember back in August of 2013 when Frame Pacing was first revealed?  Today’s Catalyst 14.1 beta release will actually complete the goals that AMD set forth upon itself in early 2013 in regards to introducing (nearly) complete Frame Pacing technology integration for non-XDMA GPUs while also adding support for Mantle and HSA capability.

Frame Pacing Phase 2 and HSA Support

When AMD released the first frame pacing capable beta driver in August of 2013, it added support to existing GCN designs (HD 7000-series and a few older generations) at resolutions of 2560x1600 and below.  While that definitely addressed a lot of the market, the fact was that CrossFire users were also amongst the most likely to have Eyefinity (3+ monitors spanned for gaming) or even 4K displays (quickly dropping in price).  Neither of those advanced display options were supported with any Catalyst frame pacing technology.

That changes today as Phase 2 of the AMD Frame Pacing feature has finally been implemented for products that do not feature the XDMA technology (found in Hawaii GPUs for example).  That includes HD 7000-series GPUs, the R9 280X and 270X cards, as well as older generation products and Dual Graphics hardware combinations such as the new Kaveri APU and R7 250.  I have already tested Kaveri and the R7 250 in fact, and you can read about its scaling and experience improvements right here.  That means that users of the HD 7970, R9 280X, etc., as well as those of you with HD 7990 dual-GPU cards, will finally be able to utilize the power of both GPUs in your system with 4K displays and Eyefinity configurations!

This is finally fixed!!

As of this writing I haven’t had time to do more testing (other than the Dual Graphics article linked above) to demonstrate the potential benefits of this Phase 2 update, but we’ll be targeting it later in the week.  For now, it appears that you’ll be able to get essentially the same performance and pacing capabilities on the Tahiti-based GPUs as you can with Hawaii (R9 290X and R9 290). 

Catalyst 14.1 beta is also the first public driver to add support for HSA technology, allowing owners of the new Kaveri APU to take advantage of the appropriately enabled applications like LibreOffice and the handful of Adobe apps.  AMD has since let us know that this feature DID NOT make it into the public release of Catalyst 14.1.

The First Mantle Ready Driver (sort of) 

A technology that has been in development for more than two years according to AMD, the newly released Catalyst 14.1 beta driver is the first to enable support for the revolutionary new Mantle API for PC gaming.  Essentially, Mantle is AMD’s attempt at creating a custom API that will replace DirectX and OpenGL in order to more directly target the GPU hardware in your PC, specifically the AMD-based designs of GCN (Graphics Core Next). 

slide2_0.jpg

Mantle runs at a lower level than DX or OGL does, able to more directly access the hardware resources of the graphics chips, and with that ability is able to better utilize the hardware in your system, both CPU and GPU.  In fact, the primary benefit of Mantle is going to be seen in the form of less API overhead and bottlenecks such as real-time shader compiling and code translation. 

If you are interested in the meat of what makes Mantle tick and why it was so interesting to us when it was first announced in September of 2013, you should check out our first deep-dive article written by Josh.  In it you’ll get our opinion on why Mantle matters and why it has the potential for drastically changing the way the PC is thought of in the gaming ecosystem.

Video Perspective: 2013 Games on the A10-7850K vs. Intel Core i3 + GeForce GT 630

The most interesting aspect of the new Kaveri-based APUs from AMD, in particularly the A10-7850K part, is how it improves mainstream gaming performance.  AMD has always stated that these APUs shake up the need for low-cost discrete graphics and when we got the new APU in the office we did a couple of quick tests to see how much validity there to that claim.

In this short video we compare the A10-7850K APU against a combination of the Intel Core i3-4330 and GeForce GT 630 discrete graphics card in five of 2013's top PC releases.  I think you'll find the results pretty interesting.

UPDATE: I've had some questions about WHICH of the GT 630 SKUs were used in this testing.  Our GT 630 was this EVGA model that is based on 96 CUDA cores and a 128-bit DDR3 memory interface.  You can see a comparison of the three current GT 630 options on NVIDIA's website here.

I know we have posted about this a few times on PC Perspective and have discussed it on the PC Perspective Podcast as well, but if you are curious as to why the prices of AMD's latest generation of R9 graphics cards have skyrocketed, look no further than this enterprising consumer and his/her Dogecoin mining rig.

AMD's first Syst-ARM on a Chip Opteron will be here soon

Subject: General Tech | January 29, 2014 - 01:16 PM |
Tagged: SoC, seattle, opteron, arm, amd, A1100

The Opteron A1100 will be the name born by AMD's first SoC, which we knew previously as Seattle and is the first chip which will contain ARM Cortex A57 architecture working in tandem with AMDs.  It will be a full 64bit chip and will sport up to 4MB of shared L2 cache and 8MB of shared L3 cache and it will support of to four DIMMs of either DDR3 or DDR4 in dual channel with ECC.  It will boot using UEFI into a Linux environment based on Fedora and will be optimized to handle web front ends and data centre tasks.  As far as connectivity it will have 8 lanes of PCIe 3.0 and 8 SATA 3 ports. You can follow links from The Register to see the AMD Press Release.

Hybrid CrossFire that actually works

The road to redemption for AMD and its driver team has been a tough one.  Since we first started to reveal the significant issues with AMD's CrossFire technology back in January of 2013 the Catalyst driver team has been hard at work on a fix, though I will freely admit it took longer to convince them that the issue was real than I would have liked.  We saw the first steps of the fix released in August of 2013 with the release of the Catalyst 13.8 beta driver.  It supported DX11 and DX10 games and resolutions of 2560x1600 and under (no Eyefinity support) but was obviously still less than perfect.  

In October with the release of AMD's latest Hawaii GPU the company took another step by reorganizing the internal architecture of CrossFire on the chip level with XDMA.  The result was frame pacing that worked on the R9 290X and R9 290 in all resolutions, including Eyefinity, though still left out older DX9 titles.  

One thing that had not been addressed, at least not until today, was the issues that surrounded AMD's Hybrid CrossFire technology, now known as Dual Graphics.  This is the ability for an AMD APU with integrated Radeon graphics to pair with a low cost discrete GPU to improve graphics performance and gaming experiences.  Recently over at Tom's Hardware they discovered that Dual Graphics suffered from the exact same scaling issues as standard CrossFire; frame rates in FRAPS looked good but the actually perceived frame rate was much lower.

drivers01.jpg

A little while ago a new driver made its way into my hands under the name of Catalyst 13.35 Beta X, a driver that promised to enable Dual Graphics frame pacing with Kaveri and R7 graphics cards.  As you'll see in the coming pages, the fix definitely is working.  And, as I learned after doing some more probing, the 13.35 driver is actually a much more important release than it at first seemed.  Not only is Kaveri-based Dual Graphics frame pacing enabled, but Richland and Trinity are included as well.  And even better, this driver will apparently fix resolutions higher than 2560x1600 in desktop graphics as well - something you can be sure we are checking on this week!

drivers02.jpg

Just as we saw with the first implementation of Frame Pacing in the Catalyst Control Center, with the 13.35 Beta we are using today you'll find a new set of options in the Gaming section to enable or disable Frame Pacing.  The default setting is On; which makes me smile inside every time I see it.

drivers03.jpg

The hardware we are using is the same basic setup we used in my initial review of the AMD Kaveri A8-7600 APU review.  That includes the A8-7600 APU, an Asrock A88X mini-ITX motherboard, 16GB of DDR3 2133 MHz memory and a Samsung 840 Pro SSD.  Of course for our testing this time we needed a discrete card to enable Dual Graphics and we chose the MSI R7 250 OC Edition with 2GB of DDR3 memory.  This card will run you an additional $89 or so on Amazon.com.  You could use either the DDR3 or GDDR5 versions of the R7 250 as well as the R7 240, but in our talks with AMD they seemed to think the R7 250 DDR3 was the sweet spot for the CrossFire implementation.

IMG_9457.JPG

Both the R7 250 and the A8-7600 actually share the same number of SIMD units at 384, otherwise known as 384 shader processors or 6 Compute Units based on the new nomenclature that AMD is creating.  However, the MSI card is clocked at 1100 MHz while the GPU portions of the A8-7600 APU are running at only 720 MHz. 

So the question is, has AMD truly fixed the issues with frame pacing with Dual Graphics configurations, once again making the budget gamer feature something worth recommending?  Let's find out!

These Aren't the Drivers You're Looking For. AMD 13.35 Leak.

Subject: General Tech, Graphics Cards | January 28, 2014 - 07:00 PM |
Tagged: Mantle, BF4, amd

A number of sites have reported on Toshiba's leak of the Catalyst 13.35 BETA driver. Mantle and TrueAudio support highlight its rumored changelog. Apparently Ryan picked it up, checked it out, and found that it does not have the necessary DLLs included. I do not think he has actual Mantle software to test against, and I am not sure how he knew what libraries Mantle requires, but this package apparently does not include them. Perhaps it was an incomplete build?

amd-not-drivers.jpg

Sorry folks, unlike the above image, these are not the drivers you are looking for.

The real package should be coming soon, however. Recent stories which reference EA tech support (at this point we should all know better) claim that the Mantle update for Battlefield 4 will be delayed until February. Fans reached out to AMD's Robert Hallock who responded that it was, "Categorically not true". It sounds like AMD is planning on releasing at least their end of the patch before Friday ends.

This is looking promising, at least. Something is being done behind the scenes.

GIGABYTE BRIX Has AMD Discrete Graphics (R9 M275X)

Subject: General Tech, Systems | January 28, 2014 - 04:54 PM |
Tagged: gigabyte brix, gigabyte, amd

If you feel a little déjà vu while reading this, it is because this system is identical to the MAINGEAR SPARK. Both devices are powered by an AMD A8-5557M APU backed with an AMD Radeon R9 M275X mobile discrete GPU. They even use the same case with the same color scheme. The only difference that I could find is the MAINGEAR logo on the front versus the GIGABYTE logo on the top. I think we could safely say that both devices are made at the same place. I expect that GIGABYTE was the OEM for MAINGEAR's Steam Machine.

Check out Tim's post about the SPARK.

Check out GIGABYTE's product page for the BRIX Gaming.

When Tim published his post about the SPARK for CES, back on January 6th, little was known about the R9 M275X (beyond its 2GB of GDDR5). That is still the case. AMD has not said anything further about the mobile GPU. The press release from GIGABYTE claims that it will support DirectX 11.1 (which implies it will not support DirectX 11.2) and OpenGL 4.1 (which implies a lack of support for OpenGL 4.2, 4.3, and 4.4). GIGABYTE also claims that it will support "the latest OpenCL 1.1 standard" (which implies lack of support for OpenCL 1.2).

I seriously doubt that this is true.

gigabyte-brix-gaming_back.jpg

I cannot see AMD regressing that heavily on API compatibility. OpenGL 4.2 has been supported since the HD 5000 (desktop) and HD 6000M (laptop) series. OpenCL 1.2 has been supported since the HD 5000 (desktop) and HD 7000M (laptop) line. One of the main features of OpenCL 1.2 is the ability share resources with DirectX 11 (OpenCL 1.1 shares with DirectX 10). In fact, I cannot find a single chip that AMD produced which supports OpenGL 4.1 and OpenCL 1.1 and fails to support OpenGL 4.2 and OpenCL 1.2.

I would not trust GIGABYTE's press release when it comes to the R9 M275X.

Still nothing on pricing and availability for the GIGABYTE BRIX Gaming. Its product code will be the "GB-BXA8G-8890", which totally rolls off the tongue, so we have that going for us. It is a very interesting device. I wonder if we will see it, and other BRIX entries, find their way into the catalogs of other system builders.

(HCW) Kaveri Overclocked +1GHz CPU, +300 MHz GPU

Subject: General Tech, Processors | January 27, 2014 - 03:24 AM |
Tagged: overclocking, Kaveri, amd

HCW does quite a few overclocking reviews for both Intel and AMD processors. This time, Carl Nelson got a hold of the high-end AMD A10-7850K and gave it a pretty healthy boost in frequencies. By the time he was done with it, the CPU was operating a whole gigahertz above stock simultaneous with a 300 MHz boost to its integrated graphics.

3DMark 2013 Fire Strike scores gained 27%.

One again, they break down tests along a suite of different games of varying engines and add some OpenCL tests to round things out. In real-world applications, the increase was not quite as dramatic as the one seen in 3DMark but still significant. This overclock allowed certain games to jump from 720p to playable at 1080p. Apparently this silicon is a decent little overclocker.
