AMD Details Renoir: The Ryzen Mobile 4000 Series 7nm APU Uncovered
AMD teased us with the broad strokes of its Ryzen 'Renoir' APU family for the mobility market at CESbut shared more details at its Ryzen Mobile Tech Day on the processors that bring the Zen 2 architecture and 7nm process to the mobility market for the first time. That includes the a new flagship 45W H-series processor along with a series of downclocked 35W HS models that the company designed primarily for high-end laptops with discrete graphics cards. These chips represent the first 7nm x86 processors for the mobile market, with the 7nm node bringing along power and performance advantages that AMD says rivals Intel's 10nm Ice Lake and 14nm Comet Lake chips. Due to Intel's continuing struggles with fully transitioning to the 10nm node, the Ice Lake chips are designed to address the gaming market with Gen11 graphics, while it positions Comet Lake processors for productivity applications due to its higher core counts. AMD takes aim at that split product family by saying that its Ryzen series processors are the no-compromise solution that address both segments with one architecture. The company also gave us more fine-grained details on Ryzen 's architectural refinements to the Zen 2 architecture and Vega graphics engine, its innovative SmartShift technology, and how it achieves its battery life claims. The laptop market comprises more than two-thirds of the overall consumer CPU market, so AMD's success in this segment is key as it continues to nibble away at Intel's desktop PC market share. AMD says its Ryzen series processors are poised to bring the company to parity, or exceed, Intel's competing chips in all of the key metrics. That includes AMD's long-held advantage in threaded workloads and graphics performance, but also now expands into challenging Intel's single-threaded prowess. AMD says it continues to make solid gains in the laptop market with a record platforms on the market inof which will come powered by the new Ryzen series processors. AMD also points to a doubling of its presence in the lucrative and fast-expanding gaming notebook segment. Let's see what's powering that growth. AMD's initial announcements covered the 15W U-series that it designed for thin and light devices that leverage the integrated Vega graphics engine, along with the 45W H-Series that comes with Vega but will often power laptops with discrete graphics cards for creators and gamers. AMD's Ryzen 9 H steps in as the highest-end of the stack. Like the rest of the Ryzen series processors, this chip comes with a monolithic die, meaning that AMD hasn't yet brought its chiplet-based architecture to the mobile space. The processor comes with eight cores, 16 threads and operates at a 3. It comes with eight Vega graphics cores that operate at a peak of MHz. This processor is slated to come to market in the spring of The HS-series processors serve as the power-optimized variants and respect a 35W power envelope but come with the same core counts and graphics engines as the H-Series models, meaning these chips are downclocked variants designed for laptops with lesser cooling solutions, which in turn enables thinner designs. The "H" denotes that these are H-series parts, while the "S" denotes that they are for slim devices. AMD says that OEMs will have to meet its standards to earn the HS branding, which includes sufficient cooling solutions to unlock the full performance of the chip, along with a quality display and performance memory. HS branded laptops also have to come with a submm thickness and provide up to 10 hours of video playback time. AMD's 7nm Renoir die comes with 9. The die is mounted to a 25x25x1. AMD chose to stick with the Vega graphics engine found in its previous-gen Picasso APUs because its hasn't optimized Navi for mobile yet, but the company chose to make several architectural enhancements when it ported Vega from the 12nm to the 7nm node. To accommodate that increased throughput, AMD doubled the width of the Infinity Fabric interconnect that ties the chips' units together. The culmination of these efforts provides up to 1. AMD says the lion's share of the improved power efficiency stems from the move to the 7nm process, but that higher frequency and architectural improvements also play a role. Controlling power consumption can be a dizzying affair in desktop chips, with thermal and electrical conditions of the chip dictating many of the power state transitions, while interactions with the operating system, BIOS and drivers all combine to help the chip modulate performance. That, in turn, dictates both frequency, sleep states, and overall power consumption. Moving that chip to a battery-powered laptop requires yet another level of sophistication that AMD addresses with a more holistic system-level approach. The net effects of these adjustments results in better power efficiency, in part due to a more clear delineation between idle and full-power states, thus eliminating unnecessary power-sapping intermediate power states. AMD's innovative Precision Boost technology, which extracts the utmost performance from each core based upon its individual capabilities, is a key technology that provides the best mixture of power and performance possible, but AMD has also developed a technique to better modulate performance and power consumption in mobile form factors. Data from these sensors is fed to the embedded controller ECwhich then transmits the telemetry data across the Infinity Fabric to the SoC. The Dynamic Power and Thermal Control DPTC interface allows external sources to adjust SoC power controls on the fly, so the system can use the data gathered from the sensors to trigger short high-frequency boosts that exceed the normal power limit, which is helpful during bursty workloads. AMD's latest advance extends that benefit to longer boost duration periods. The System Temperature Tracking V2 STT V2 feature manages power state transitions based on a multitude of factors, like the external skin temperature, allowing the laptop to sustain up to four times longer boost periods without becoming uncomfortably hot for the user. Notably, Intel's modern laptop processors take a similar approach of adjusting power states based on external temperature sensors. That enables finer-grained control of the various states, thus allowing the SoC to make better decisions that translate to improved power efficiency and battery life.

Now, this has changed. One new model laptop that is an example of this is the 3. This model will have several different configurations, but the review samples mostly seem to have one configuration. The naming scheme that AMD is using is confusing, for no good reason. You can also replace the stock PCIe 3. Intel now has some real competition in the mobile space. Overall, the reviews that I have read and watched have been overwhelmingly very positive. Here are a few that you might want to read or watch:. AMD has put a lot of pressure on Intel in the desktop CPU space, and is a huge favorite among people who like to build their own machines from parts. This is interesting, but has not been a huge blow to Intel, because the desktop CPU market is relatively small. AMD has been successful in certain market segments, but Intel has completely dominated the very important mobile market segment. This will give people more choices, and will force Intel to respond or face losing market share. The initial response will probably be price cuts, while long-term, Intel will have to release better products. This is good news for anyone who is looking for a new laptop. If you find this sort of content interesting, please let me know in the comments. Thanks for reading! It is pretty impressive to have a relatively small and light laptop compete so well with much larger laptops that use CPUs that draw double the power. AMD Ryzen 9 H.

HW News: AMD Renoir Mobile CPUs
Pre-orders are going to start in the coming days and the reviews are slated to go live no earlier than April. AMD today also confirmed the existence of the top-end Ryzen 9 SKUs with higher operating frequencies and souped-up graphics. However, these will be released at a later date tentatively Q2. First the low power 15W Ryzen U lineup:. As you can see the 15W U series is the focus. The reason being that slim form-factor notebooks are everywhere these days. Pretty every application from gaming to browsers leverage up to 8 cores nowadays. The Ryzen 5 and 7 have two variants each. Both are hex-core parts while one features SMT along with a slightly lower base clock. It also has a snazzy rear-panel with moveable LEDs, something akin to an equalizer. As you can see, the H series ditches the lower-end Ryzen 3 variant. AMD is probably leaving the U series chips for the average user while the H series will serve power-users and gamers. This clearly evident from the corresponding core counts. The former offers a lot more variety with cores while the latter is essentially a two-product catalog, one with twelve threads while the other with sixteen. Interestingly, the Ryzen 7 U features one more graphics core than the H. We covered that in a post earlier, you can catch it here:. Compared to the desktop Ryzen series, Renoir features a reduced L3 cache. In addition to this, the Ryzen parts also get a healthy MHz H boost in terms of the core clock which will have a meaningful impact in real-world scenarios especially gaming. They feature an insane 9. As far as the fine-grained architectural details are concerned, the same improvements to the front-end and back-end of the core are present as the desktop Ryzen lineup. You can read more here:. The graphics part of things is less interesting but equally impressive. However, thanks to the super-efficient 7nm node, AMD has been able to extract a lot more performance out of the old graphics parts. The overall FP32 compute horsepower increases from 1.
