Meet the AMD Trinity/Comal Prototype Laptop

So I have to be honest: I’m a sucker for unique laptops. Not so much from the standpoint of actually using such laptops, but just as something cool to show my fellow computer nerds when they visit. The Trinity prototype is quite clearly a design that isn’t going to market without some changes, but unlike the Llano prototype (or the Intel SNB prototype), at least this one tries to stand out from the crowd a little bit. AMD has gone all-in on branding, with the AMD logo featured prominently on the cover, below the LCD on the bezel, and at the top-left of the keyboard. None of that makes the design any better from a functionality standpoint, but it’s still a cool tchotchke:

The bottom of the laptop is full of the usual warning about how the laptop may not meet regulatory requirements (and if you think that sticker is bad, you should see some of the dire warnings in the documentation for another prototype I’ve got hanging about waiting for the NDA to lift!). There’s also a bold “Prototype System” label, and the Blu-ray drive is clearly of a not-for-resale nature, with a fascia that doesn’t line up with the laptop shell. None of this affects the performance of the laptop, but it’s a nice diversion for what is otherwise an unremarkable system. In terms of specifications, just for completeness’ sake here’s the full rundown of the system components:

Everything is pretty much standard fare these days, though it’s interesting that AMD chose to ship us a laptop with an SSD drive instead of a regular HDD. You’ll note that we list two SSDs as well as two sets of memory; the reason is that we performed additional performance testing with hardware that’s slightly different than AMD’s shipping configuration. We wanted to make our comparisons with other laptops more apples-to-apples, so we used the memory from the Ivy Bridge laptop we recently reviewed to see if doubling the RAM made any difference for our benchmarks—it didn’t. We also tested five different laptops with a 240GB Intel 520 SSD, just to level the playing field for tests like PCMark.

The PCMark scores for the Samsung 830 and Intel 520 are within 1% of each other, and for most systems it’s really going to come down to a question of whether you have an SSD or not rather than what specific SSD you’re using. You may (or may not) be surprised to hear that the bigger impact from the SSD came in the area of battery life. The ASUS N56VM battery life remained essentially unchanged with the Intel 520 instead of the original 750GB 7200RPM Seagate HDD, so if you expect any SSD to improve battery life you might be surprised by that result. The other surprise was just how much of a difference there was between the Samsung 830 and Intel 520 SSDs in the Trinity laptop: the Samsung 830 improved battery life by nearly 10% in two out of three tests (and by 3% in the H.264 playback test). A quick look at the idle power consumption results from our SSD Bench provides the answer, of course: the 128GB Samsung 830 uses just 0.38W at idle compared to 0.82W for the 240GB Intel 520. For a desktop, it’s hardly worth mentioning, but for laptops that nearly half a watt definitely shows up.

We could complain about the usual items like build and LCD quality—neither one is particularly impressive for this test laptop—but they really don’t matter since this isn’t a retail sample. For the intended purpose, the laptop works fine—fix the optical drive bezel and I’m sure there would even be some enthusiasts interested in owning a piece of genuine AMD laptop kit. But since that’s not going to happen, let’s move on from the laptop and run some actual performance tests.

Test Setup

Before we get to the charts, let’s quickly discuss the list of laptops we’ve selected for this review. There’s always some debate and outcry over what we include/omit in the charts, which is one of the reasons we have Mobile Bench—you can perform any head-to-head comparison there if you’d like. With well over 100 laptop results in our Mobile Bench database, sifting through the complete charts can be a bit of a nightmare, so for our articles we try to prune things down. I settled on ten laptops for the majority of our charts, with an attempt to represent most of the interesting data points.

Naturally we have AMD’s Trinity prototype (highlighted in red), and to go along with the newest and latest hardware we’ve also included results from Intel’s quad-core Ivy Bridge notebook (in dark green). It’s important to consider that these two laptops do not target the same market: we expect the ASUS N56VM to sell for around $1200 with the tested configuration, whereas AMD’s Trinity laptops will hopefully be closer to half that price—obviously, without shipping hardware we really don’t know what OEMs will end up charging for Trinity. To fill in the rest of the charts, we have two AMD Llano laptops (orange)—one the original AMD prototype, only this time equipped with an SSD, and the second a standard Toshiba Satellite P755D. We’ve also got two primary Sandy Bridge comparisons (light green): one is the prototype quad-core i7-2820QM, and the second is a retail Dell Vostro V131 with i5-2410M; the only catch is that we retested both systems with the Intel 520 SSD.

Rounding out the rest of the selections, we have three ultrabooks: the Acer TimelineU with NVIDIA GT 640M graphics, a Dell XPS 13 with i7-2637M, and a Toshiba Z830 with i3-2367M. All three of these come with SSDs, and we thought it would be interesting to show where Trinity falls relative to the low and high marks set by Sandy Bridge ultrabooks. The last laptop in the list is Sony’s VAIO SE, which has switchable graphics with AMD’s HD 6630M. Given the i7-2640M CPU, the VAIO SE should give a pretty clear look at the maximum performance you can get from the discrete Radeon HD 6630M GPU, so we’ll be able to see if/when Trinity’s HD 7660G comes out ahead of previous generation mobile GPUs. All four of these laptops are in blue—our default “don’t pay too much attention to me” color.

    I think it *needs* to be at $600 to sell, because SNB + GT 540M is already at $600. However, HP has hinted that their sleekbooks with Trinity will start at $600 and $700 for the 15.6" and 14" models, respectively. "Start at" and "comes with a reasonable amount of RAM and an A10 APU" are not the same thing. Until HP actually lists full specs and a price, I have to assume that the $600 price tag for the 15" model is going to be 4GB RAM, 250GB HDD, and an A6-4400 APU. Hopefully I'm wrong, but the fact is we don't know Trinity's real price yet, so in the article I'm referring to the price I think it should be at in order to provide a good value. Reply

    As most people I assume are coming from the Core 2 Duo style laptops, I would like to see a comparison of trinity with that.

    I know core i processors are fast, but I don't know if AMD has caught up with Core 2 performance.

    Even with Llano they had caught up, with Trinity the margin will only be larger. Use this to compare whatever you want

    How about comparing Llano to a core 2 quad? And at about the same frequency.
    Here you go:

    Sorry to be rude. I really think you missed the point of this chip.

    The CPU in Trinity is close to a 17W CPU with a 17W GPU. It performs about the same as an intel 17W chip. It's graphics engine is far better and the CPUs should cost about the same. The only real disadvantage over 17W Sandy Bridge is that in a prototype chasis Trinity uses more power, but a few watts should be shaved on production models.

    This means AMD has caught up to Intel again! Yes AMD is going to lose spectacularly when ULV Ivy Bridge comes out and I doubt Trinity is going to scale at higher power but at low power, AMD has caught up!

    (Yes I know that Sandy Bridge includes a GPU but if you look at your benchmarks, ULV Intel with a dGPU scores similar to Trinity when transcoding [The only really CPU limited test in this review])

    Something I just read at The Tech Report: when using MediaEspresso to transcode video, the result of VCE was much smaller than QuickSync or software, yet they didn't notice a difference in quality. I would like to know what your experience was. If that's really the case I'd prefer VCE over other Intel's solution even if it's slower. Reply
  • Riek - Wednesday, May 16, 2012 - link

    As far as i know VCE is not yet supported or been made available by AMD.

    All those tests are due to openCL and not VCE since that part cannot be reached at this point in time. (yes blame AMD for that one, this is already taking 6months and still their is nothing about VCE)

    You're mistaken, there.

    Quote from Page 2:
    "Trinity borrows Graphics Core Next's Video Codec Engine (VCE) and is actually functional in the hardware/software we have here today. Don't get too excited though; the VCE enabled software we have today won't take advantage of the identical hardware in discrete GCN GPUs"

    When you go to the llano review, the HD4000 gets stomped by Llano's desktop graphics offering. When you look at Trinity, the notebook version of trinity barely beats Llano. Why is it that Intel can practically fit the full power of their IGP (get nearly the same performance from notebooks as from 3770k) but AMD's is drastically weaker?

    Also - will we see a weaker HD4000 in the dual core/cheaper IVB variants? I think Trinity desktop GPU will stomp on the HD4000 and might actually be a viable budget gaming solution as long as CPU improvements are good enough. We could see it take down quite a bit of the discrete graphics market I think, considering the HD4000 already can do that.

    It's an odd move by Intel, perhaps, but I think it makes sense. The mobile Sandy Bridge and Ivy Bridge parts basically get the best IGP Intel makes (HD 3000/4000), and what's more the clocks are just as high and sometimes higher than the desktop parts. Yeah, how's that for crazy? The i7-3720QM laptop chips run HD 4000 at up to 1.25GHz while the desktop i7-3770/K/S/T runs the IGP at up to 1.15GHz. SNB wasn't quite so "bad" with HD 3000, as the 2600K could run HD 3000 at 1.35GHz compared to 1.3GHz on the fastest mobile chips.

    Anyway, the reason I say it kind of makes sense is that nearly all desktops can easily add a discrete GPU for $50-$100, and it will offer two or even three times the performance of the best IGP right now. On a laptop, you get whatever the laptop comes with and essentially no path to upgrade.

    For AMD, if you look at their clocks they have them cranked MUCH higher on desktops. The maximum Llano clocks for mobile chips are 444MHz, but the desktop parts are clocked up to 600MHz. What's even better for desktop is that Llano's GPU could be overclocked even further on many systems -- 800MHz seems to be achievable for many. So basically, AMD lets their GPU really stretch its legs on the desktop, but laptops are far more power/heat constrained. It will be interesting to see what AMD does with desktop Trinity -- I'd think 900MHz GPU core speeds would be doable.
