Every now and then, a content piece falls to the wayside and is archived indefinitely -- or just lost under a mountain of other content. That’s what happened with our AMD Ryzen pre-launch interview with Sam Naffziger, AMD Corporate Fellow, and Michael Clark, Chief Architect of Zen. We interviewed the two leading Zen architects at the Ryzen press event in February, had been placed under embargo for releasing the interview, and then we simply had too many other content pieces to make a push for this one.
The interview discusses topics of uOp cache on Ryzen CPUs, power optimizations, shadow tags, and victim cache. Parts of the interview have been transcribed below, though you’ll have to check the video for discussion on L1 writeback vs. writethrough cache designs and AMD’s shadow tags.
“Good for streaming” – a phrase almost universally attributed to the R7 series of Ryzen CPUs, like the R7 1700 ($270 currently), but with limited data-driven testing to definitively prove the theory. Along with most other folks in the industry, we supported Ryzen as a streamer-oriented platform in our reviews, but we based this assessment on an understanding of Ryzen’s performance in production workloads. Without actual game stream benchmarking, it was always a bit hazy just how the R7 1700 and the i7-7700K ($310 currently) would perform comparatively in game live-streaming.
This new benchmark looks at the AMD R7 1700 vs. Intel i7-7700K performance while streaming, including stream output/framerate, drop frames, streamer-side FPS, power consumption, and some brief thermal data. The goal is to determine not only whether one CPU is better than the other, but whether the difference is large enough to be potentially paradigm-shifting. The article explores all of this, though we’ve also got an embedded video below. If video is your preferred format, consider checking the article conclusion section for some additional thoughts.
Specs and prices for AMD’s upcoming Ryzen Threadripper CPUs have been announced, as well as a general release date. The 12C/24T 1920X and 16C/32T 1950X will be available worldwide starting in “Early August,” with prebuilt Alienware systems available for preorder starting July 27th. According to AMD:
“Both are unlocked, use the new Socket TR4, have quad-channel DDR4, and feature 64 lanes of PCI Express. Base clock on the Ryzen Threadripper 1950X 16-core product is 3.4 GHz with precision boost to 4.0 GHz. On the Ryzen Threadripper 1920X 12-core product, the base clock is 3.5 GHz with precision boost to 4.0 GHz.”
As an aside, manufacturers informed GamersNexus at Computex that board release dates are targeted for August 10. It’s possible that this date has changed in the time since the show, but that seems to be the known target for Threadripper.
Our newest revisit could also be considered our oldest: the Nehalem microarchitecture is nearly ten years old now, having launched in November 2008 after an initial showing at Intel’s 2007 Developer Forum, and we’re back to revive our i7-930 in 2017.
The sample chosen for these tests is another from the GN personal stash, a well-traveled i7-930 originally from Steve’s own computer that saw service in some of our very first case reviews, but has been mostly relegated to the shelf o’ chips since 2013. The 930 was one of the later Nehalem CPUs, released in Q1 2010 for $294, exactly one year ahead of the advent of the still-popular Sandy Bridge architecture. That includes the release of the i7-2600K, which we’ve already revisited in detail.
Sandy Bridge was a huge step for Intel, but Nehalem processors were actually the first generation to be branded with the now-familiar i5 and i7 naming convention (no i3s, though). A couple features make these CPUs worth a look today: Hyperthreading was (re)introduced with i7 chips, meaning that even the oldest generation of i7s has 4C/8T, and overclocking could offer huge leaps in performance often limited by heat and safe voltages rather than software stability or artificial caps.
This week's hardware news recap primarily focuses on industry topics, like new NAND from Toshiba, Western Digital, and a new SSD from Intel (first 64-layer VNAND SSD). A few other topics sneak in, like AMD's Ryzen Pro CPU line, a Vega reminder (in the video), the death of Lexar, and a few gaming peripherals.
Through the weekend, we'll be posting our Zotac 1080 Ti Amp Extreme review, the first part of our AMD Vega: Frontier Edition Hybrid mod, and a special benchmark feature in our highly acclaimed "Revisit" series.
In the meantime, here's the last week of HW news recapped:
This episode of Ask GN posts on the tail of the X299 and Kaby Lake X / Skylake X embargo lift and in the midst of the newest cryptocurrency craze, which has set upon the video card market like a swarm of locusts.
We’re addressing two general questions we’ve seen around the internet, then following-up with reader/viewer-submitted questions. If you’d like to pose a question for the next Ask GN, the best place to do so would be in either our Patreon discord or in the video comments.
We asked Intel why Kaby Lake-X exists at its recent press day, challenging that the refreshed 7700 & 7600 CPUs can’t be used on LGA1151 sockets, that they aren’t significantly different from the predecessors, and that LGA2066 boards are way more expensive. The socket and chipset alone have a higher BOM cost for manufacturers than 200-series boards, and that cost is passed on to consumers. That’s not free. The consumer also pays for the components that won’t go unused, like the trace routing for half of the DIMMs (and the physical slots).
But Intel gave us an answer to that query.
Keeping marketing checked by reality is part of the reason that technical media should exist: Part of the job is to filter out the adjectives and subjective language for consumers and get to the objective truth. Intel’s initial marketing deck contained a slide that suggested their new X-series CPUs could run 3-way or 4-way GPUs for 12K Gaming. Those are their exact words: "12K Gaming," supported by orange demarcation for the X-series, whereas it is implicitly not supported (in the slide) on the K-SKU desktop CPUs. Not to speak of how uncommon that resolution is, this also isn’t a real resolution. Regardless, we’re using this discussion of Intel’s "12K" claims as an opportunity to benchmark two x8 GPUs on a 7700K with two x16 GPUs on a 7900X, with some tests disabling cores and boosting clock. We have also received a statement from Intel to GamersNexus regarding the marketing language.
First of all, we need to define a few things: Intel’s version of 12K is not what you’d normally expect – in fact, it’s actually fewer pixels than 8K, so the naming is strongly misleading. Let’s break this down.
Our hardware news round-up for the past week is live, detailing some behind-the-scenes / early information on our thermal and power testing for the i9-7900X, the Xbox One X hardware specs, Threadripper's release date, and plenty of other news. Additional coverage includes final word on Acer's 21X Predator, Samsung's 64-layer NAND finalization, Global Foundries' 7nm FinFET for 2018, and some extras.
We anticipate a slower news week for non-Intel/non-AMD entities this week, as Intel launched X299/SKY-X and AMD is making waves with Epyc. Given the command both these companies have over consumer news, it's likely that other vendors will hold further press releases until next week.
Find the show notes below, written by Eric Hamilton, along with the embedded video.
Intel’s past few weeks have seen the company enduring the ire of a large portion of the tech community, perhaps undeservedly in some instances -- certainly deservedly in others. We criticized the company for its initial marketing of the 7900X – but then, we criticize nearly everyone for marketing claims that borderline on silly. “Extreme Mega-Tasking,” for instance, was Intel’s new invention.
But it’d be folly to assume that Skylake-X won’t perform. It’s just a matter of how Intel positions itself with pricing, particularly considering the imminent arrival of Threadripper. Skylake-X is built on known and documented architecture and is accompanied by the usual platform roll-out, with some anomalies in the form of Kaby Lake X's accompaniment on that same platform.
Today, we're reviewing the Intel Core i9-7900X Skylake X CPU, benchmarking it in game streaming (Twitch, YouTube) vs. Ryzen, in Blender & Premiere rendering, VR gaming, and standard gaming.
