MSI Radeon HD 7790 OC Edition: Mid-Range Graphics

4 thumbs up
Just before the mid-range AMD Radeon HD 7790 hit store shelves in early April, NVIDIA countered with the GeForce GTX 650 Ti BOOST. NVIDIA’s move also involved pricing changes that were good for mid-range card shoppers, but what matters most is that the card NVIDIA managed to launch coincident with the Radeon HD 7790’s launch, offers better performance in most of our benchmarks. With the dust settling, all that’s left now is for the factory-overclocked cards to battle it out.

Asus and Sapphire have already taken a crack with their overclocked Radeon HD 7790s. Those cards definitely out-perform the stock-clocked Radeon HD 7790 we tested in March, but couldn’t always overcome the NVIDIA GeForce GTX 650 Ti BOOST. Today, we’re looking at the MSI Radeon HD 7790 OC Edition (R7790-1GD5/OC), which has a slightly lower base clock speed of 1,050MHz than its Asus and Sapphire counterparts. The frame buffer is also clocked a touch slower, but keep in mind that the MSI 7790 is set to street at around $135 (currently listing for $139 on Amazon after rebate), while the Asus and Sapphire cards are priced at $154.99 and $159.99, respectively.

As we mentioned, MSI’s Radeon HD 7790 has a core clock speed of 1,050MHz. The card also has 1GB of GDDR5 memory and a memory clock right at 6Gbps. That’s really not much slower than the memory bandwidth offered by the other cards; our Asus and Sapphire boards offer 6.4Gbps. But it’s enough to mean a slight edge for those cards in the benchmarks, as we’ll see on the following pages.

As a mid-range card, the MSI Radeon HD 7790 has a modest footprint in your system – though it will take up two slots at the back of your chassis. The card is 7.17 inches long x 4.16 inches tall, and 1.5 inches across, thanks to the cooling shroud on one side. That shroud covers copper heat pipes and an aluminum heatsink, all of which is cooled by a surprisingly quiet fan. According to MSI, the fan features its proprietary “Propeller Blade Technology,” which provides 20% more airflow than your average graphics card fan.

MSI also touts the quality of the card’s components, garnering it the company’s own “Military Class III” rating, because the card meets the U.S. MIL-STD-810G durability standard. Marketing-speak aside, this is a feature worth looking for in your components, particularly when you plan to undertake overclocking.

The MSI Radeon HD 7790 is powered by a single six-pin PSU connector and the Thermal Design Power requirement is 100W. For output, the card offers two DVI ports, an HDMI port, and a DisplayPort. It supports resolutions up 2560x1600 and handles DirectX 11 and OpenGL 4.2. And, of course, the card has support for AMD’s CrossFire. The card includes two physical accessories: an external power cable and a DVI/D-Sub adapter.

Before we dig into MSI’s software bundle, we should point out that the card is selling on some retailers with a limited-time bundle that includes a couple of noteworthy titles: BioShock Infinite and Far Cry 3 Blood Dragon. That bundle also includes a copy of Futuremark’s new 3DMark benchmarking tool.

As for the MSI software typically included with the video card, you’re looking at a Norton Internet Security trial, MSI Afterburner, MSI Dual Core Center, MSI Live, and MSI StarOSD. The most important of these applications is Afterburner, which is MSI's popular, robust overclocking utility. The program has overclocking profiles that let you quickly kick your card into overdrive when you’re ready to fire up a game (or even switch in-game), and it includes tools for logging the card’s status and identifying important info, like the BIOS version. The utility also has a video-capture feature called Predator for recording your game sessions.

Not to belittle MSI and their card or anything, but these factory overclocked cards, in many cases, just don't offer enough increased performance to just the additional cost. Sure, they're great for people who don't want to tinker with their clock speeds, but it isn't like it is difficult to get a card with a nice, capable cooler and use an aftermarket tool to do the overclocking yourself. Or spend the same amount of cash, or a smidge more, and buy the next model card up instead. :)

Not to belittle MSI and their card or anything,

MSI is great.

A card that's OC'd by the factory still carries a warranty at the faster speeds. If ~you~ OC a card and fry it, it's not covered. I understand that a lot of us tweak our cards a little bit more than what they come set at.

Also, an OC'd card usually already has better than stock cooling on it.

FYI, I have this card and it overclocks to 1225 core clock, 1662 (6648 effective) memory clock with no problems. If you can manage to sell the two crappy games it comes with on Ebay, then this card is a steal.

Good review but hardly useful to the folk looking to spending $120-170 for two reasons…

It's inappropriate to assume "cards in this class" can run with such levels of graphic quality or even test 2560x resolution when isn't providing real world inference.  I mean none of the cards that logically fall into the competition of a 7790 are really providing good playable results on Ultra/AAx4/AFx16 settings (perhaps Metro, Batman).  Mostly the rest of the results aren’t telling folks much, they know they'll need/should "concede" on some settings.

Beside the settings, the CPU (i7 Hyper-Threading) and system, is far from what anyone envisioning stuffing a $120-170 card with.  Now almost every site testing video cards runs max system spec's so, not to have CPU bottle necks which is understandable. I can't chastise you that’s what most do, but between settings and system spec’s what you provide is nothing like what most buying this should ever intend to appreciate.  It would be far better for a site like yourselves' to start this review saying; we are going to test this "class" of cards with a modest, may I say normal system that folk looking at hardware of this level would be using. 

I've found only one other site that tested that way, and the outcome is quite surprising.  Your charts just communicate what every other reviewer shows, this "class of card" aren't capable of enthusiast level of eye-candy.  Although, you could be the one showing just a little tuning back on one or so settings can still provides an exhilarating experience with just "entry level box".  Buyers and the graphic card companies would rather have you revealing what can be done with a $120-170 card gaming than basically showing they perform as well as more expensive cards.
