We spoke exclusively with the Creative Assembly team about its game engine optimization for the upcoming Total War: Warhammer. Major moves to optimize and refactor the game engine include DirectX 12 integration, better CPU thread management (decoupling the logic and render threads), and GPU-assigned processing to lighten the CPU load.
The interview with Al Bickham, Studio Communications Manager at Creative Assembly, can be found in its entirety below. We hope to soon visit the topic of DirectX 12 support within the Total War: Warhammer engine.
PAX East 2016 has a strong hardware presence, and the number of zero-hour announcements backs that up. MSI, Corsair, AMD (a first-time exhibitor at East), nVidia, Intel, Cooler Master, Kingston, and a handful of other hardware vendors have all made an appearance at this year's show, ever flanked by gaming giants.
Today's initial news coverage focuses on the MSI Aegis desktop computer, Corsair's updated K70 & K65 keyboards, and the AMD Wraith cooler's arrival to lower-end SKUs. Find out more in the video below:
The AMD Athlon X4 880K is the CPU we've been waiting for. Since the A10-7870K and A10-7860K APU reviews, our conclusions have generally been pointing in this direction. For the dGPU-using gaming audience, it makes better sense for budget buyers to grab a cheap CPU and dGPU than to buy an APU alone. There is a place for the APUs – ultra-budget, tiny, quiet HTPCs capable of video streaming and moderate gaming – but for more “core” gaming, the CPU + dGPU move currently does yield major gains. Even just throwing a 250X at an APU has, in some of our tests, nearly doubled gaming performance. For such a dirt-cheap video card, that's a big gain to be had.
And so AMD's Athlon X4 880K enters the scene. The price is all over the map right now. MSRP is $95 from AMD, but the X4 880K isn't (as of this writing) available through major first-party retailers like Amazon and Newegg. We've seen it for $104 from third-party Newegg sellers, but as low as $90 from sites we've never heard of, if you count those. In theory, though, the X4 880K will eventually come to rest at $95.
The new CPU is effectively a step between the 7870K and 7890K, but with the IGP disabled. This lowers validation cost while offering effectively equivalent CPU performance. AMD's X4 880K operates on a two-module, four-core Excavator architecture with a stock clock-rate of 4.0 to 4.2GHz (boosted). For comparison, the A10-7890K runs 4.1 to 4.3GHz, so there's a 100MHz gain over the X4 880K. Easily negated with overclocking, as the 880K is a K-SKU, multiplier-unlocked chip. The 880K has a 95W TDP and is paired with AMD's 125W near-silent (NS) cooler.
This review and benchmark of the Athlon X4 880K tests thermals, gaming (FPS) performance, and compares against higher-end i3 & i5 CPUs, APUs, and the old X4 760K.
This fifteenth episode of Ask GN springs forth a few quick-hitter questions, but a couple that require greater depth than was addressable in our episodic format. These longer questions will be explored in more depth in future content pieces.
For today, we're looking at the future of AMD's Zen for the company, forecasting HDR and monitor tech, discussing IGP and CPU performance gains, and talking thermals in laptops. As always, one bonus question at the end.
Timestamps are below the embedded video.
We’re covering the Graphics Technology Conference in San Jose this week – a show overflowing with low-level information on graphics silicon and VR – and so have themed our Ask GN episode 14 around silicon products.
This week’s episode talks CPU thread assignment & simultaneous multi-threading, VR-ready IGPs, the future of the IGP & CPU, and Dx12 topics. We also briefly talk Linux gaming, but that requires a lengthier, future video for proper depth.
If you’ve got questions for next week’s episode, as always, leave them below or on the video comments section (which is where we check first).
Stutter as a result of V-Sync (which was made to fix screen tearing -- another problem) has been a consistent nuisance in PC gaming since its inception. We’ve talked about how screen-tearing and stutter interact here.
Despite the fact that FPS in games can fluctuate dramatically, monitors have been stuck using a fixed refresh rate. Then nVidia’s G-Sync cropped-up. G-Sync was the first way to eliminate both stutter and screen-tearing on desktop PCs by controlling FPS-refresh fluctuations. Quickly after nVidia showed off G-Sync, AMD released their competing technology: FreeSync. G-Sync and FreeSync are the only adaptive refresh rate technologies currently available to consumers on large.
We welcomed AMD's Scott Wasson on-camera at the company's Capsaicin event, where we also spoke to Roy Taylor about driver criticism and covered roadmap updates. Wasson was eager to discuss new display technology demonstrated at the event and highlighted a critical shift toward greater color depth and vibrancy. We saw early samples of HDR screens at CES, but the Capsaicin display was far more advanced.
But that's not all we spoke about. As a site which prides itself on testing frame delivery consistency (we call them “low frametimes” – 1% and 0.1% lows), it made perfect sense to speak with frametime testing pioneer Scott Wasson about the importance of this metric.
For the few unaware, Wasson founded the Tech Report and worked as the site's Editor-in-Chief up until January, at which time he departed as EIC and made a move to AMD. Wasson helped pioneer “frametime testing,” detailed in his “Inside the Second” article, and we'd strongly recommend a read.
AMD's GPU architecture roadmap from its Capsaicin event revealed the new “Vega” and “Navi” architectures, which have effectively moved the company to a stellar naming system. A reasonable move away from things associated with hot, at least – Volcanic Islands, Hawaii, and Capsaicin included.
Video card drivers are almost as important as the hardware with which they interface; without stable and ongoing driver support, a GPU can't be fully utilized to a level that exercises its strengths in the field. AMD has long battled to improve perception of its drivers – a fight we endorsed upon the release of Catalyst successor Radeon Settings – and has continued that battle at GDC 2016.
“For a long time, people keep saying, 'well, AMD has great hardware – what about our drivers?'” AMD Corporate VP Roy Taylor told us in an interview, “I don't want to hear that anymore, all right?” The response was given in our interview following AMD's Capsaicin event, which featured industry luminaries in game development and VR.
AMD just announced a partnership with Total War developers Creative Assembly, highlighting the game developer's move to implement DirectX 12 with the upcoming Total War: Warhammer Grand Strategy game.
