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.

If you are looking for more information on AMD's Kaveri APUs you should check out my review of the A8-7600 part as well our testing of Dual Graphics with the A8-7600 and a Radeon R7 250 card.

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.

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.

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!

Not only are the first Kaveri reviews arriving today, the A10-7850K is up for sale on both NewEgg and Amazon and the A10-7700K is available on NewEgg.  This new part, at 45W competes favourably with the previous 100W Trinity APU in most tests and when Ryan boosted it to 65W it gained a little more.  The Steamroller cores have been updated but not in a way that has a huge effect on CPU performance, on the other hand the 384 SIMD units composing the GPU portion of this chip are quite impressive, 1080p gaming of current generation titles is possible on this chip and we haven't seen it's big brother with 512 SIMD units yet.  In the Tech Report's review you can see that BF4 is playable on this chip and this is not the Mantle version optimized for AMD's new architecture.  It is also a pity that Thief was unavailable to see just what TrueAudio is capable of.  Unfortunately this chip will not find its home in gamers dream machines, that is simply not where AMD is targeting its CPUs.  However, for SFF systems that need to be energy efficient and where a discrete GPU is to big to fit Kaveri will usher in a new level of performance.

"AMD's next-generation APU packs in a ton of innovation, including updated "Steamroller" CPU cores, GCN graphics, and advanced HSA features. But is it enough to restore AMD's competitiveness in desktop processors?"

The AMD Kaveri Architecture

Kaveri: AMD’s New Flagship Processor

How big is Kaveri?  We already know the die size of it, but what kind of impact will it have on the marketplace?  Has AMD chosen the right path by focusing on power consumption and HSA?  Starting out an article with three questions in a row is a questionable tactic for any writer, but these are the things that first come to mind when considering a product the likes of Kaveri.  I am hoping we can answer a few of these questions by the end of this article, but alas it seems as though the market will have the final say as to how successful this new architecture is.

AMD has been pursuing the “Future is Fusion” line for several years, but it can be argued that Kaveri is truly the first “Fusion” product that completes the overall vision for where AMD wants to go.  The previous several generations of APUs were initially not all that integrated in a functional sense, but the complexity and completeness of that integration has been improved upon with each iteration.  Kaveri takes this integration to the next step, and one which fulfills the promise of a truly heterogeneous computing solution.  While AMD has the hardware available, we have yet to see if the software companies are willing to leverage the compute power afforded by a robust and programmable graphics unit powered by AMD’s GCN architecture.

(Editor's Note: The following two pages were written by our own Josh Walrath, dicsussing the technology and architecture of AMD Kaveri.  Testing and performance analysis by Ryan Shrout starts on page 3.)

Process Decisions

The first step in understanding Kaveri is taking a look at the process technology that AMD is using for this particular product.  Since AMD divested itself of their manufacturing arm, they have had to rely on GLOBALFOUNDRIES to produce nearly all of their current CPUs and APUs.  Bulldozer, Piledriver, Llano, Trinity, and Richland based parts were all produced on GF’s 32 nm PD-SOI process.  The lower power APUs such as Brazos and Kabini have been produced by TSMC on their 40 nm and 28 nm processes respectively.

kv01.jpg

Kaveri will take a slightly different approach here.  It will be produced by GLOBALFOUNDRIES, but it will forego the SOI and utilize a bulk silicon process.  28 nm HKMG is very common around the industry, but few pure play foundries were willing to tailor their process to the direct needs of AMD and the Kaveri product.  GF was able to do such a thing.  APUs are a different kind of animal when it comes to fabrication, primarily because the two disparate units require different characteristics to perform at the highest efficiency.  As such, compromises had to be made.

AMD CES 2014 Presentation: Kaveri Goes Official

This year’s AMD CES was actually more interesting than I was expecting.  The details of the event were well known, as most Kaveri details have been revealed over the past few months.  I was unsure what Lisa Su and the gang would go over, but it was actually more interesting than I was expecting.

kav01.jpg

This past year has been a big one for AMD.  They seem to be doing a lot better than others expected them to, especially with all of the delayed product launches on the CPU side for quite a few years.  This year saw the APU take a pretty prominent place in the industry with the launch of the latest generation consoles from Sony and Microsoft.  AMD made inroads with mobile form factors with a variety of APUs.  The HSA Foundation members have grown and HSA members ship two out of every three connected, smart devices.  Apple also includes Firepro graphics cards with all of their new Mac Pros.

Kaveri is of course the big news here.  AMD feels that this is the best APU yet.  The combination of Steamroller CPU cores, GCN graphics compute cores, HSA, hUMA, HQ, TrueAudio, Mantle support, PCI-E 3.0 support, and a configurable TDP makes for a pretty compelling product.  AMD has shuffled some nomenclature about by saying that Kaveri, at the top end, is comprised of 12 compute cores.  These include 4 Steamroller cores and 8 GCN compute clusters.  Each compute cluster matches the historical definition of a core, but of course it looks quite a bit different than a traditional x86 core.

kav02.jpg

We have gone over Kaveri pretty extensively in the past.  The CPU is clocked at 3.7 GHz with a 4 GHz boost.  The graphics portion clocks in at 720 MHz.  It can support up to DDR-3 2400 MHz memory, which is really needed to extract as much performance out of this new APU.  Benchmarks provided by AMD show this product to be a big jump from the previous Richland, and in these particular benchmarks are quite a bit faster than the competing i5 4670K.

Gaming performance is also improved.  This APU can run most current applications at 1080P resolutions with low to medium quality settings.  Older titles can be run at 1080P with Medium to High/Extreme settings.  While this processor is rated at around 867 GFLOPS, which is around 110 GFLOPS greater than the previous top end Richland, it is more efficient at delivering that theoretical performance.  It looks to be a significant improvement all around.

kav03.jpg

Software support is improving with applications from companies like Adobe, The Document Foundation, and Nuance.  These cover HSA applications and in Nuance’s case, using the TrueAudio portion to clean up and accelerate voice recognition.  TrueAudio is also being supported in five upcoming games.  This is not a huge amount, but it is a decent start for this new technology.

Mantle is gaining a lot more momentum with support from 3 engines, 5 developers, and 20+ games in development.  They showed off Battlefied 4 running Mantle on a Kaveri APU for the first time publicly.  They mentioned that it ran 45% faster than Direct3D at the same quality levels on the same hardware.  The display showed frame rates up in the low 50 fps area.

kav04.jpg

AMD is continuing to move forward on their low power offerings based on Beema and Mullins.  Lisa claims that these parts are outperforming the Intel Baytrail offerings in both CPU performance and graphics.  Unfortunately, she mentioned noting about the power consumption associated with these results.  They showed off the Discovery tablet as well as a fully functional PC that was the size of a large cellphone.

They closed up the even by talking about the Surround House 2.  This demo looks significantly better than the previous iteration we saw last year.  This features something like a 34.2 speaker setup in a projected dome.  It is much more complex than the House from last year, but the hardware running it all is rather common.  A single high end Firepro card running on a single A10 7850K.  The demo is also one of the first shows of a 360 degree gesture recognition setup.

kav05.jpg

AMD has come a long way since hitting rock bottom a few years back.  They continue to claw their way back to relevance, and they hope that Kaveri will help them regain a foothold in the computing market.  They are certainly doing well in the graphics market, but the introduction of Kaveri should help them gain more momentum in the CPU/APU market.  We have yet to test Kaveri on our own, but initial results look promising.  It is a better APU, but we just don’t know how much better so far.

AMD A10-7850K and A10-7700K Kaveri Leaks Including Initial GPU Benchmarks

Subject: General Tech, Graphics Cards, Processors | December 3, 2013 - 04:12 AM |
Tagged: Kaveri, APU, amd

The launch and subsequent availability of Kaveri is scheduled for the CES time frame. The APU unites Steamroller x86 cores with several Graphics Core Next (GCN) cores. The high-end offering, the A10-7850K, is capable of 856 GFLOPs of compute power (most of which is of course from the GPU).

Image/Leak Credit: Prohardver.hu

We now know about two SKUs: the A10-7850K and the A10-7700K. Both parts are quite similar except that the higher model is given a 200 MHz CPU bump, 3.8 GHz to 4.0 Ghz, and 33% more GPU units, 6 to 8.

But how does this compare? The original source (prohardver.hu) claims that Kaveri will achieve an average 28 FPS in Crysis 3 on low at 1680x1050; this is a 12% increase over Richland. It also achieved an average 53 FPS with Sleeping Dogs on Medium which is 26% more than Richland.

These are healthy increases over the previous generation but do not even account for HSA advantages. I am really curious what will happen if integrated graphics become accessible enough that game developers decide to target it for general compute applications. The reduction in latency (semi-wasted time bouncing memory between compute devices) might open this architecture to where it can really shine.

We will do our best to keep you up to date on this part especially when it launches at CES.

Xbox One Teardown - Microsoft still hates you

Last week we brought a teardown of the new Sony PlayStation 4 (PS4) console and this week we do the same for Microsoft's new Xbox One console. 

In this video, which is a recording of our live stream that started last night at 12:30am EST, you'll see us unbox the Xbox One, turn it on, play with the new Kinect, take it apart and put it back together.  And this time we didn't even break anything - though removing the plastic clips on the Xbox One are particularly more annoying and time consuming than the screws on the PS4.

Though they are out of stock, Amazon.com appears to be getting additional Xbox One consoles in stock pretty regularly, so keep an eye out.

The 7 Year Console Refresh

Be sure you jump to the second page to see our recommendations for gaming PC builds that are inexpensive yet compete well with the capabilities and performance of the PlayStation 4 and Xbox One!!

The consoles are coming!  The consoles are coming!  Ok, that is not necessarily true.  One is already here and the second essentially is too.  This of course brings up the great debate between PCs and consoles.  The past has been interesting when it comes to console gaming, as often the consoles would be around a year ahead of PCs in terms of gaming power and prowess.  This is no longer the case with this generation of consoles.  Cutting edge is now considered mainstream when it comes to processing and graphics.  The real incentive to buy this generation of consoles is a lot harder to pin down as compared to years past.

ps4apu.jpg

The PS4 retails for $399 US and the upcoming Xbox One is $499.  The PS4’s price includes a single controller, while the Xbox’s package includes not just a controller, but also the next generation Kinect device.  These prices would be comparable to some low end PCs which include keyboard, mouse, and a monitor that could be purchased from large brick and mortar stores like Walmart and Best Buy.  Happily for most of us, we can build our machines to our own specifications and budgets.

As a directive from on high (the boss), we were given the task of building our own low-end gaming and productivity machines at a price as close to that of the consoles and explaining which solution would be superior at the price points given.  The goal was to get as close to $500 as possible and still have a machine that would be able to play most recent games at reasonable resolutions and quality levels.

Last night Ken and I headed over the local Best Buy to pick up my preorder of the new Playstation 4.  What would any hardware geek immediately do with this hardware?  Obviously we take a screwdriver to it and take it apart.

In this video, which is a recording of our live stream that started last night at 12:30am EST, you'll see us unbox the PS4, turn it on, take it apart and put it back together.  And I only had to fix one piece with gaffers tape, so there's that.

(We'll have a collection of high-resolution photos later today as well.)

Though they are out of stock, Amazon.com appears to be getting more PS4s in stock pretty regularly, so keep an eye out if you are interested in picking one up still.

Happy Friday!
