Haswell and GK110 vs. Ivy and GK104: DigitalStorm Virtue System Reviewby Dustin Sklavos on June 23, 2013 12:00 PM EST
Introducing the DigitalStorm Virtue
One of the biggest benefits of doing system reviews from boutiques like DigitalStorm is the chance to see what talented builders do with brand new hardware once it's released into the wild. Single consumers/enthusiasts get used to and understand the range of performance typically available in overclocking retail kit, but boutiques have to contend with overall performance potential of a range of products on a larger scale. Whether or not you get a decent overclock on your i7-4770K isn't a huge deal; you bought the chip, you're good to go. But for a boutique it becomes a more serious issue, defining their advertising and ultimately helping us all paint a fairly broad picture of what we can expect or at least hope for from new kit.
If you're like me, you were probably incredibly underwhelmed by initial reviews of Haswell. Ivy Bridge proved to be a decent overclocker, but Intel's miserly switch from fluxless solder to thermal paste as a thermal interface material in their chip packaging put a hard limit on what we could really do with it, and they're continuing that aggavating trend with Haswell. One of the most frustrating results is a flattening of the overclocked performance curve from Sandy Bridge to Ivy Bridge, and thankfully we can at least test and see today if Haswell does anything to change things.
With the recent refresh of our benchmarking suite (I carry over notebook benchmarking to the desktop and then add a surround test), I realized we had a perfect opportunity to test just how much progress we've made from one generation to the next. One of the perks of working in the industry is access to high end kit; my personal desktop workstation isn't just fun to have, it also serves as an extremely useful reference platform that I can now pit DigitalStorm's attractive new micro-ATX mid-tower, the Virtue, against.

Starts at $1,403
Review system configured at $2,563
DigitalStorm has four configurations for the Virtue, starting at $1,403. The entry level offers a basic quad core Haswell with no overclocking and a GeForce GTX 650 Ti Boost; it's adequate for gaming, but informed consumers will want the second level model featuring an i5-4670K and GeForce GTX 770 for $1,735. Worth mentioning, though, is that DigitalStorm offers a 120GB Corsair Neutron GTX SSD and 1TB HDD minimum, across the board, in all configurations of the Virtue. The highest end model bumps the SSD capacity up to 240GB and the GPU to a GeForce GTX Titan.
There isn't too much to say about the Virtue as we have it, though. DigitalStorm was able to eke out a healthy 4.4GHz overclock on the i7-4770K, but the overclock range they offer is just 4GHz to 4.4GHz, which is underwhelming to say the least. That's not their fault, though; iBuyPower only goes up to about 4.2GHz, ~4.5GHz if you're using one of their signature custom liquid cooling systems. CyberPowerPC offers roughly the same "20% overclock" which works out, again, to about 4.2GHz. DigitalStorm's overclocking options are also essentially in line with AVADirect and other boutiques; Haswell just doesn't have a whole lot of headroom. Meanwhile, DigitalStorm does offer performance tuning on their graphics cards, but the GTX 780 in our review unit is left at stock.
Representing the best and brightest of the last generation is my own custom workstation which will be referred to in charts as the "Reference PC." This is, in my humble opinion, about as good as it can get before you switch over to a custom cooling loop.

(4x3.5GHz, Turbo to 3.9GHz, Overclocked to 4.6GHz, 22nm, 8MB L3, 77W)

|Power Supply||Rosewill Capstone 750W 80 Plus Gold PSU|
|Operating System||Windows 8 Professional 64-bit|
Case modified with Noctua fans
CPU cooled by Swiftech H220
GPU cooled by Arctic Cooling Accelero Hybrid
When you get to the benchmarks, you'll see this is really about as fast as a last generation, single-GPU configuration with a mainstream CPU was going to get. 4.6GHz is healthy for Ivy Bridge, and the Arctic Cooling Accelero Hybrid allowed the GeForce GTX 680 to not only settle on a high boost clock, but maintain it consistently throughout prolonged gaming sessions. This is with the stock GTX 680 BIOS; a modified BIOS with higher voltage might have been able to push the silicon further, but I've heard exactly enough about modified BIOSes burning out GK104 to not tempt fate

HideOut - Sunday, June 23, 2013 - linkThat 5ghz chip is also 220w part. Not even close to relevant to most reasonable pc users. It's a marketing gimmick.
wumpus - Monday, June 24, 2013 - linkThe computer in question has a 250W GPU and a 1000W power supply, there is no reason to veto a 220W CPU. While I think the Nvidia 780 is a "marketing gimick" (pretty much the same additional performance/cost), it seems to be a minority opinion on this site.
MrSpadge - Monday, June 24, 2013 - linkThat 220 W is the reason Intels dismisses such CPUs, as they'd hardly sell at all. How ever would be interested in such beasts is already covered with the current Ks and Extremes, including factory OC'ed builds.
Klimax - Tuesday, June 25, 2013 - link220W which won't beat my 3930k on conservative overclocking 4.4GHz and which is most likely cheaper...
MrSpadge - Monday, June 24, 2013 - linkThat's rubbish. Super low temperatures always help FETs to work significantly faster. That's why the clock speeds reached with LN2 will NEVER be possible in production untits of the same fundamental technology.
And if Intel designed for significantly higher clock speeds they'd loose IPC due to the longer pipeline and would blow the power efficiency gains Intel worked so hard on during the last years completely out of the window. Just remember the Pentium 4 or nVidias hot clock versus Kepler.
Nintendo Maniac 64 - Sunday, June 23, 2013 - linkContrary to what everyone is saying, I and several others have discovered that Haswell is surprising fast at emulation - around 20% faster than Ivy and 30% faster than Sandy. If would be great if a review site like Anand would actually benchmark such programs because they are heavily CPU-oriented and currently are one of if not the only compelling reason for Haswell and it'd be a shame if people missed that memo.
This forum topic summarizes what I describe:
Sabresiberian - Sunday, June 23, 2013 - linkYeah I agree from an enthusiast viewpoint that Haswell is a little underwhelming, and am irritated that Intel kept the glue-on method of attaching covers, but there are apps in which it crushes Ivy Bridge - and none in which Ivy Bridge is superior.
As always, buy your hardware for the applications you most want to support. :)
JDG1980 - Sunday, June 23, 2013 - linkI agree that emulators could work well as CPU benchmarks, especially since many of them are single-threaded or lightly-threaded (so they're a real-world application where IPC is important).
PCSX2 running Dragon Quest 8 would be a good benchmark. It uses two CPU threads (three if MTVU is enabled) and is very demanding, especially in busy scenes.
Gigaplex - Monday, June 24, 2013 - linkRunning PCSX2 on potentially pirated games for a commercial review is legally dubious at best.
p1esk - Sunday, June 23, 2013 - linkSo what is exactly the value DigitalStorm brings to the table?
It seems to me that they put together a few off the shelf components, and slightly bumped up the frequency. Is that all? If so, that's something anyone who reads this site can do themselves in an hour or less.
What I expect from a "boutique" computer builder is systems like the new Mac Pro, only where I can customize everything and anything.
Otherwise, no, they don't deserve extra $200-300 on top of Newegg BOM.
