Our last head-to-head GPU comparison benchmarked the performance of a single GTX 980 Ti versus two GTX 970s in SLI. Following some astute reader suggestions, we've acquired a PowerColor Devil 13 dual-core R9 390 – two GPUs on one card – to test as a CrossFire stand-in against SLI GTX 970s. Performance analysis is accompanied by power draw and thermal tests, though a proper, full review on the Devil 13 card will follow this content in short order.

For today, the focus is on this head-to-head comparison. FPS benchmarks look at performance of 2x CrossFire R9 390s vs. 2x SLI GTX 970s, including supporting data from a GTX 980 Ti, 980, and R9 390X. We'll also work toward answering the question of whether CrossFire and SLI are worth it in this particular scenario, as opposed to investing in a single, more expensive GPU.

AMD R9 Nano Price Drops to $500

Monday, 11 January 2016

Following its Polaris GPU architecture announcement and ensuing Polaris demo at CES, AMD today announced a reduction in price for its R9 Nano video card. The card, which launched in September 2015, is now carrying a Suggested Etail Price (SEP) of $500, a significant drop from its $650 launch price (the same as the Fury X).

It normally takes a few days for SEP reductions to set-in at Amazon and Newegg, but the two major retailers should soon reflect this change.

AMD’s new Polaris architecture discretely sat in the company’s CES 2016 suite, running Star Wars Battlefront with impressively low system power consumption. Quietly the GPU sat, running a completely new architecture and process for GPUs. No fanfare, no bombastic marketing videos projected on the walls, no product unveil insanity.

The demo was simple: Show two Intel i5 Haswell systems side-by-side, one with an nVidia GTX 950 ($160) and one with AMD’s undisclosed Polaris GPU. AMD locked framerate to 60FPS in the demo, showing both GPUs at a constant 60FPS using the X-Wing Survival map (singleplayer), and directing focus toward Kill-A-Watt wall meters. The wall meters show total system watt consumption and, as one would expect from an AMD suite, the AMD-powered system ran at lower total system power consumption overall.

Quick Disconnect (QDC) liquid cooling has been concepted a few times before. For the enthusiast and DIY market, there’s not been much of an uptake on the QDC quasi-open loop liquid cooling – but there’s also never been a major marketing push. Our CES 2016 visit with EVGA had us hands-on with a quad-SLI + CPU quick disconnect liquid cooling setup, taking from the well-received GTX 980 Ti Hybrid design and expanding into sequential liquid cooling.

EVGA’s roadmap for 2016 includes quick disconnect GPUs, CPU blocks, and radiators, with additional product support in cases, power, boards, and audio. We’re focusing on the QDC components and  the case today.

Graphics manufacturer AMD and its Radeon Technologies Group (RTG) today announced the arrival of “Polaris,” a 14nm FinFET architecture derived from codename Arctic Islands. Polaris is due in mid-2016 and supersedes the aged 28nm process, which both major GPU manufacturers presently employ. The new node should drastically impact performance-per-watt, aided by FinFET transistors (shaped like a 'fin,' rather than planar, so containment of power is more efficient – i.e., less leakage).

Scalable multi-card configurations from both nVidia and AMD have improved in their performance over the years, with both companies investing additional resources to driver optimizations for multi-card users. The value of SLI or CrossFire has always been debatable, particularly for day-one system builders (rather than someone upgrading), but is worth investigating further. With all the year's newest titles – and some mainstays with well-tested performance – we did that investigation, specifically comparing a single 980 Ti vs. 2x 970s in SLI, a 980, single 970, and R9 390X for AMD baseline.

Today's GTX 970 SLI vs. single 980 Ti test benchmarks average FPS and 1% / 0.1% low performance, presenting data in a few different chart types: Usual AVG, 1% low, & 0.1% low head-to-head performance; delta value (percent advantage) between the 970s in SLI and 980 Ti; delta value (percent gain) between the 2x 970s and a single GTX 970.

Aside from some odd encounters in the Fury X department and poor initial driver support, AMD's continued R9 roll-out has increasingly improved in its competitive posturing. We've already looked at the R9 380X as provided by Sapphire and remarked that we felt “confident in recommending” AMD's newest device. Today, we're moving to PowerColor's PCS+ R9 380X, a dual-fan-cooled 380X chip with a slight pre-overclock, but significant overhead for additional clock increases.

Our benchmark reviews the PowerColor R9 380X Myst Edition graphics card vs. Sapphire's R9 380X Nitro, including FPS, thermal, and OC testing.

For a review of the R9 380X as it compares to other cards – like the similarly-priced GTX 960 – we'd recommend our R9 380X review and individual game benchmarks (including ACS, Battlefront, Fallout, and more). This review specifically looks at the PCS+ 380X as it compares to our other R9 380X, the Sapphire Nitro card.

AMD CEO Lisa Su recently indicated that the company's Radeon R9 Fury dual-GPU card would be pushed into 2Q16, a marked delay over the initial EOY 15 target launch window.

The new card will host two Fiji GPUs on a single card, potentially imbuing the dual-GPU, single-card market with a bit of life. The device has been touted since E3 as the Fiji Gemini and was targeting a December launch period, with Lisa Su claiming that the delay has been to better accommodate shipment of virtual reality products (HTC Vive coincides with the new Gemini window).

This article specifically looks at single-GPU solutions to gaming at various price-points. We scale our GPU search from $100 to $600, covering PC builders across budget, mid-range, and high-end configurations. We've had extensive hands-on testing with the cards below, a fact accentuated by the burst of game launches in the past few weeks. Most of these cards have been tested in Battlefront, Fallout 4, AC Syndicate, Black Ops III, and the year's earlier titles, like The Witcher 3 and GTA V.

Black Friday starting to hit full swing, we found some of the best graphics cards of the year on sale for – in some cases – significant discount. The GTX 970 at $290, R9 380 at $143, and GTX 980 at $400 are just a few of the finds below.

Jon Peddie Research today released its independent GPU shipment analysis, its highlights including an averaged 9% growth in GPU shipping volume, despite a year-over-year desktop GPU shipment decline of 13%.

JPR has released these reports before. The research firm includes Intel's IGPs and AMD's APUs whenever mentioning “GPU shipments” or “GPU sales,” unless otherwise noted in their documentation. This fact is important to understand why some of the metrics appear the way they do.
