The Ryzen 3 CPUs round-out AMD’s initial Ryzen offering, with the last remaining sector covered by an impending Threadripper roll-out. Even before digging into the numbers of these benchmarks, AMD’s R3 & R5 families seem to have at least partly influenced competitive pricing: The Intel i3-7350K is now $150, down from its $180 perch. We liked the 7350K as a CPU and were excited about its overclocking headroom, but found its higher price untenable for an i3 CPU given then-neighboring i5 alternatives.
Things have changed significantly since the i3-7350K review. For one, Ryzen now exists on market – and we’ve awarded the R5 1600X with an Editor’s Choice award, deferring to the 1600X over the i5-7600K in most cases. The R3 CPUs are next on the block, and stand to challenge Intel’s freshly price-reduced i3-7350K in budget gaming configurations.
This week's hardware news recap covers rumors of Corsair's partial acquisition, HBM2 production ramping, Threadripper preparation, and a few other miscellaneous topics. Core industry topics largely revolve around cooler prep for Threadripper this week, though HBM2 increasing production output (via Samsung) is also a critical item of note. Both nVidia and AMD now deploy HBM2 in their products, and other devices are beginning to eye use cases for HBM2 more heavily.
The video is embedded below. As usual, the show notes rest below that.
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.
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:
Following AMD’s Computex press conference, we headed over to the Gigabyte suite (after our X299 coverage) to look at the X399 Aorus Gaming 7 motherboard. The new Gigabyte X399 Gaming 7 board is one of two that we’ve seen thus far – our ASUS coverage is next up – and joins the forces of motherboards ready for AMD’s Threadripper HEDT CPUs.
The Gigabyte X399 Aorus Gaming 7 motherboard sockets Threadripper into AMD’s massive socket, dead-center, and uses three Torx screws to get at the LGA pin-out. The CPUs will provide 64 PCIe lanes, as we’ve already reported, with 4x PCIe Gen3 lanes reserved for high-speed transport between the CPU and chipset. The other 60 are assignable at the motherboard manufacturer’s will; in this case, Gigabyte willed for an x16/x8/x16/x8 full-length PCIe slots, with an additional 3x M.2 (x4) slots. That immediately consumes all 60 lanes, with the remaining 4 reserved for the chipset communications.
AMD hosted its financial & analyst day today, revealing information on Vega, Threadripper, notebook deployments of its CPUs & GPUs, and data center products. Some timelines were loosely laid-out with initial benchmark previews, provided an outline for what to expect from AMD in the remainder of 2017.
Most of our time today will be spent detailing Vega, as it’s been the topic of most interest lately, with some preliminary information on the CPU products.
We came away from our revisit of the once-king Sandy Bridge 2600K and 2500K CPUs impressed by the staying power of products that came out in Q1 2011, considering Intel’s unimpressive gains since that time.
At the time of Sandy Bridge’s release, AMD’s flagship CPUs were 45nm K10-based Phenom IIs, designed to compete in price/performance with the 45nm Lynnfield (Nehalem i5) quad cores. Later that year, AMD’s underwhelming Bulldozer architecture would launch and inevitably replace the Phenom line. Given that we’ve already looked at Intel’s 1Q11 offerings, we decided to revisit AMD’s Phenom II CPUs in 2017, including the Phenom II X6 1090T (Black Edition) and Phenom II X6 1055T. These benchmarks look at AMD Phenom II performance in gaming and production workloads for the modern era, including comparisons to the equal-aged Sandy Bridge CPUs, modern Ryzen 5 & 7 CPUs, and modern Intel CPUs.
It’s been a few months since our last PC build--in fact, it was published well before Ryzen was released. For our first post-Ryzen build, we’ve pulled together some of the components we liked best in testing to make an affordable ultrawide gaming machine. As we did in January, we pulled parts out of inventory and actually assembled and tested this PC to back up our recommendations--we’ll try to continue doing this going forward.
This gaming PC build is priced at just over $1000 -- about $1200, depending on rebates -- and is made for UltraWide 3440x1440 gaming. Our goal is to take reasonably affordable parts and show that UltraWide 1440p gaming is feasible, even while retaining high settings, without buying the most expensive GPUs and CPUs on the market. We’re only using parts in this build that we actually have, so that partially dictates cost (yes, you might be able to do some things cheaper -- like the motherboard), but it also means that we’ve had time to build, validate, and use the system in a real environment. In these early days of Ryzen as a new uarch, that’s important. We’ve done the hard work of troubleshooting a functional build. All you’d have to do is assemble it, configure BIOS, and go.
As a note: This build is also readily capable of production workloads. CUDA acceleration on the GTX 1070 will work well for Premiere renders, and the CPU thread-count will assist in CPU acceleration (like for streaming).
