AMD's A10-5750M Review, Part 2: The MSI GX60 Gaming Notebookby Dustin Sklavos on June 29, 2013 12:00 PM EST
Introducing the MSI GX60
Gaming notebooks are increasing in popularity, but getting affordable gaming hardware can still be a challenging task. While midrange parts like NVIDIA's GeForce GT 740M and 750M or AMD's Radeon HD 8600M line aren't bad options and will definitely do the job in a pinch, having a good gaming experience generally requires more muscle. Whether you want to boost minimum framerates for smoother play or just turn on all the bells and whistles, a strong GPU is critical. Unfortunately, a strong GPU also costs money.
MSI introduced its first-generation GX60 gaming notebook some time towards the end of last year as a way to bridge the gap. If you were willing to take a hit in CPU performance by using a Trinity-based AMD A10-4600M, you could be served by a very powerful AMD Radeon HD 7970M on the graphics side. Budget gamers on the desktop will often cut CPU budget if it means getting a faster graphics card, and that's the principle MSI is operating off of.
The fly in the ointment is that the gaming landscape has changed substantially since the first GX60. Games like Far Cry 3, Crysis 3, and Tomb Raider are all true next generation titles, requiring a healthy amount of CPU horsepower along with their substantial graphics requirements. As we saw in the first part of our review of the AMD A10-5750M, AMD has made some headway in CPU performance compared to last generation's Trinity chips, but we're still dealing with fundamentally the same silicon.

As far as mobile AMD chips go, the A10-5750M is about as fast as it gets. Trinity and Richland did away with the 45W parts you could find in the Llano generation, so we're essentially hoping that the pair of Piledriver modules running at a 2.5GHz nominal clock speed can pick up enough slack to power the AMD Radeon HD 7970M.
That Radeon HD 7970M is essentially the MSI GX60's reason for being. MSI went all-in on the graphics side, and an updated model of the GX60 is due soon that bumps the 7970M to an 8970M. The 7970M is based on AMD's Pitcairn desktop chip: it features 1,280 of AMD's GCN cores running at a healthy 850MHz clock rate, along with 80 texture units and 32 raster operators. Our review unit features 2GB of GDDR5 on a 256-bit memory bus running at 4.8GHz. If you're concerned our test results with the 7970M are going to be outdated when the 8970M-enabled GX60 lands, fear not: the only difference is a 50MHz boost clock on the 8970M. The chip is otherwise identical. Performance-wise, the 7970M and 8970M should stack up somewhere between the desktop HD 7850 and 7870, leaning more towards the 7870.
Where I'm a bit frustrated with the MSI GX60 is in both the memory configuration and the storage configuration. All told this is basically a smaller version of the GT70 chassis, less the backlit keyboard, but MSI opted to only include one DIMM instead of two for the memory, and we're stuck with a mechanical hard disk for storage duties. Thankfully you can get the GX60 for $1,199, which is a pretty good deal for a system with such a powerful GPU at its heart, and that does take some of the edge off.
Since the first part of the Richland review focused on the AMD A10-A5750M with dual-channel memory enabled, we have an opportunity now to compare those CPU results to the stock results of the GX60, which runs in only single-channel mode.

JarredWalton - Sunday, June 30, 2013 - linkMy testing suggests otherwise. Despite having 20 EUs vs. 16 EUs, HD 4400 and HD 4600 are generally about the same performance as HD 4000. I've even got a quad-core standard voltage i7-4700MQ system (MSI GE40), and surprisingly there are several games where the HD 4600 iGPU fails to be a significant upgrade to an ULV HD 4000 in and i5-3317U. I'm not sure if Intel somehow changed each EU so that the Haswell EUs are less powerful relative to IVB, but outside of driver optimizations (it's still early in the game for Haswell) I have no good reason for the lack of performance I'm getting from HD 4600.
sheh - Monday, July 1, 2013 - linkThe i7-4500U review showed not much of a difference at times, and even slightly lower performance, but +20% in other cases. i7-4770 vs i7-3770 shows more improvement. I'm guessing the improvement in a 37W CPU would be more like the desktop parts rather than the 15W CPU. But, well, all theoretical anyway.
TheinsanegamerN - Saturday, June 29, 2013 - linkits a little problematic, i think. they are ultrabook cpus, and bga to boot. it's cheaper to make laptops with rpga connectors than soldering the cpu to the motherboard. until rpga models appear (not likely) we might not see that many. they are also $100 more expensive than ultrabook models from last year, so a lot of maufacturers are still using ivy. toshiba just brought out 3 new laptops, two are ultrabooks, all which use ivy instead of haswell.
TheinsanegamerN - Saturday, June 29, 2013 - linknever mind, just found list that included socketed models. guess the oems are just slow
IntelUser2000 - Saturday, June 29, 2013 - linkThe SV dual cores are actually Q4, so its quite a few bit left. They are planning on phasing it out in favor of U chips, where it Broadwell it disappears entirely.
sheh - Sunday, June 30, 2013 - linkOn the forum you said Q4 is rumors, any more concrete info since then?
arthur449 - Saturday, June 29, 2013 - linkI wouldn't sell or buy a laptop if it didn't have all its available memory channels populated. This entire review is pointless to me.
JarredWalton - Saturday, June 29, 2013 - linkBecause buying an extra 8GB DIMM for $75 or whatever is too hard? And it will only help with iGPU performance?
arthur449 - Saturday, June 29, 2013 - linkMainstream CPUs have used a dual channel memory controllers for so long that simply disabling access to one channel can have (as we've seen in this case) a not insignificant effect on benchmarks that do not directly stress the GPU portion of the chip. CPUs have had uses for more memory bandwidth before there were on-chip GPUs, afterall.
Furthermore, in scientific terms, due to the author changing two variables in this experiment (var1a: iGPU. var 1b: dual channel. var2a: dGPU. var2b: single channel.) to compare the iGPU to the dGPU, we cannot be certain that the subtraction of the second channel of memory has a non-zero effect on dGPU performance.
If the author's intention was merely reviewing the out-of-the-box performance of this hardware configuration of the MSI GX60 Gaming Notebook, this would be fine. Instead, the article is titled: "AMD's A10-5750M Review: ..."
I'm not trying to be unnecessarily harsh. And the subject of this review could very easily apply to my interest. (I *just* purchased a laptop for a family member with an AMD A8-5550M.) But if the author is going to test the processor's gaming performance: don't change more than one variable.
TheinsanegamerN - Saturday, June 29, 2013 - linkthe single channel ram should be fine in this case, since its not used for video at all. at least its 1600mhz
