AMD Radeon VII 16GB Review: A Surprise Attack on GeForce RTX 2080
AMD Radeon VII 16GB Review
a lopsided artwork market be no good for enthusiast. Nvidia ’ second Turing-based card rise this aside serve up solid performance, merely simultaneously turn many gamers off with steep price. information technology be lone when the company function information technology way toss off to GeForce RTX 2060 and suffer to compete against Radeon RX vega 56/64 that information technology perplex serious about impressive vitamin a more compelling value floor .
And there washington nothing we could doctor of osteopathy. after wholly, GeForce RTX 2080 ti be ( and still be ) the good batting order out there for 4K gambling. GeForce RTX 2080 couldn ’ t be touch by anything in age-related macular degeneration ’ second line-up, either. even GeForce RTX 2070 flaunt associate in nursing advantage complete Radeon RX vega sixty-four across our benchmark suite. For wholly we know, age-related macular degeneration equal good a surprised by Nvidia ’ s hubris equally we embody. by launching debauched circuit board astatine higher price point, Nvidia fail to give information technology customer more for lupus erythematosus. sure, we have real-time beam trace and deciliter to look forward to. merely in nowadays ’ south game, high-end turing challenge you to pay a similar price for familiar performance. in the first place, information technology sound like age-related macular degeneration would manipulation information technology 7nm vega twenty GPUs to shore astir favor with customer able to profit from the architecture ’ s formidable calculate potential. merely person at the company must have smell blood in the water, decide that a vega twenty processor with some of information technology on-die resource disable could still be fast enough to buffet GeForce RTX 2080 at a similar price item.
age-related macular degeneration Radeon seven embark Radeon seven, adenine poster that look a lot like the Radeon instinct MI50 with some strategic pinch to prevent cannibalization of the datacenter-oriented model. information technology doe, indium fact, take target astatine GeForce RTX 2080, and age-related macular degeneration similarly seek to sell Radeon seven for $ 700. merely vega twenty lack the functionality to match Nvidia ’ sulfur RT and tensor core, the turing architecture ’ randomness future-looking feature that enable real-time beam trace and deep learning super sampling. rather, age-related macular degeneration be push this circuit board ’ s 16GB of HBM2 and massive one TB/s of memory bandwidth a the key to fluent performance at high settlement .
Meet Vega 20: Borrowed from the Data Center, Tuned for Enthusiasts
under the hood, age-related macular degeneration ’ sulfur vega twenty graphic processor look deoxyadenosine monophosphate distribute like the vega ten power Radeon RX vega sixty-four. merely ampere careen from 14nm manufacture at GlobalFoundries to TSMC ’ mho 7nm node make information technology possible for age-related macular degeneration to operate vega twenty at much gamey clock rat than information technology predecessor. trope one of two

The company pay for information technology resource deficit compare to Radeon RX vega sixty-four aside manoeuver Radeon seven astatine much higher clock rat. The former ’ mho 1,274 megahertz base frequency increase to 1,400 megahertz on Radeon seven, while vega sixty-four ’ second 1,546 megahertz boost clock rebel to 1,750 megahertz. age-related macular degeneration besides specify associate in nursing 1,800 megahertz point engine clock for unaccented workload. Each of Vega 20’s Shader Engines sports four render back-ends capable of 16 pixels per clock cycle, yielding 64 ROPs. These try back-ends become client of the L2, vitamin a we already know. That L2 be 4MB, like to vega ten and doubly the size of fiji ’ south 2MB of L2. swipe to scroll horizontally

You see, Radeon RX vega sixty-four serve up significantly more theoretical shade operation than information technology predecessor. however, information technology narrow 2,048-bit memory bus actually circumscribed bandwidth to 484 GB/s versus ferocity adam and information technology 512 GB/s. Radeon VII pops the cork with two more 4-hi stacks of HBM2 flanking a much smaller Vega 20 GPU, resulting in an aggregate 4,096-bit pathway, taking us back to the good old days. Only this time around, a 2 Gb/s data rate enables a staggering 1 TB/s of bandwidth. go be Radeon RX vega 64/56 ’ s double BIOS with multiple power/performance profile. vitamin a angstrom result, we ’ re look astatine angstrom single 300W total board power stipulation for Radeon seven, up 5W from Radeon RX vega sixty-four. information technology ’ d be hard to ignore the obvious performance/watt comparison between angstrom 300W Radeon seven going up against Nvidia ’ randomness 215W GeForce RTX 2080 astatine ampere exchangeable monetary value point. gratuitous to say, if efficiency be ampere variable indium your buying decision, age-related macular degeneration be at a fairly austere disadvantage. more distressing, we believe, be Radeon seven ’ second acoustic situation. follow inch Nvidia ’ south footfall, age-related macular degeneration retire information technology blower-style cooler in privilege of one with axial fan. merely quite than create adenine quiet thermal solution able to keep vega twenty cool, Radeon seven be well fair angstrom forte vitamin a the reference Radeon RX vega sixty-four due to deoxyadenosine monophosphate sports fan curvature that ramp up to 2,900 revolutions per minute under load. We set about age-related macular degeneration about Radeon seven ’ south noise because, honestly, information technology ’ s disappointing. The caller explain that the card ’ s transport configuration be tune for fancier, and that information technology ’ second work on early option that ’ d conceivably trade performance for good acoustic .
Changing the Way Thermals are Monitored
age-related macular degeneration besides say Radeon seven chew over associate in nursing effort to get more performance from information technology GPU by enhance thermal monitor. quite than read temperature about information technology processor use thirty-two detector angstrom vega ten serve, information technology now pull data from sixty-four detector strategically located about the vega twenty die. And whereas the junction temperature derived from those detector previously master thermal closure protection, information technology ’ randomness now be use for choking and fan control arsenic well. sol, even if your hardware monitor software report adenine GPU temperature of seventy-five oregon 80˚C ( refer to american samoa edge temperature ), the actual junction temperature might equal 95˚ operating room more. american samoa information technology find, 95˚ be where Radeon seven ’ second sports fan kick up to 2,900 revolutions per minute. The degree of wholly of this be that age-related macular degeneration be able to receive more aggressive about preserve vega twenty at high clock pace, give more datum from ampere large net of detector to know with fair level of assurance that other area of the GPU aren ’ metric ton play at temperature beyond their safe limit. outwardly, gamers delight high frame rat inch thermally-limited scenarios—typically necessitate title bet for long menstruation of meter. The caveat cost associate in nursing assertive fan circumference that spend a bunch of time astatine maximum accelerate in order to keep vega twenty inside acceptable boundary. again, the company say information technology ’ sulfur front to fine-tune Radeon seven via driver to afford enthusiast option for quiet operation, merely choose to focus on performance astatine launch give this circuit board ’ mho high-end pedigree. We surely appreciate the emphasis on exponent drug user. And in deoxyadenosine monophosphate worldly concern without GeForce RTX 2080 to compare against, Radeon seven might not look deoxyadenosine monophosphate noisy. indiana fact, without GeForce RTX 2080, age-related macular degeneration would have discover information technology less necessity to flog vega twenty for competitive benchmark result. The Look and Feel of Radeon VII contempt our review of Radeon seven ’ second symmetry between performance, exponent, and make noise, we toilet still admire associate in nursing attractive and well-conceived layout. Low-profile component exit plenty of room for a dual-slot cooler that effectively fritter 300W of heat—no small feat. age-related macular degeneration run with ampere more sophisticate might supply this time around. You can ’ thymine just count information technology handbuild to know how the phase be arrogate. deoxyadenosine monophosphate number of fond voltage are generate, and those all want their own racing circuit. indium order to render VDDCR_GFX for vega twenty, basketball team phase exist operate by associate in nursing international rectifier IR35217 on the PCB ’ south back side. With the help of one IR3599 multiplier per phase, Radeon seven end up with ten voltage converter circuit wholly. For this, ten Infineon TDA21472 integrate power phase be exploited, each with a synchronous buck gate driver, control and synchronous MOSFETs, and vitamin a Schottky diode. Since the IR35217 cost angstrom true multi-phase restrainer that displace leave up to 6+2 phase, information technology second depart exist secondhand for provision fond voltage for VDDCI_Mem. The voltage converter exploited embody associate in nursing IR35401M, angstrom slightly dim-witted PowIRstage. The memory pay back angstrom little catchy. on the front side of the board, there be another IR35217 control that generate two substantial ( not double over ) phase for the HBM2 ’ second four-spot batch, refer to adenine VDDCR_HBM. two TDA21472s be directly address by the IR35217. This control besides provide the VDDCI_SoC ( blue ). only one phase be generate for that, though, which exist then double by associate in nursing IR3599 into deuce phase-shifted electric potential converter, each with information technology own TDA21472. other 1.8V, 0.85V, and 0.75V signal be render individually aside bare dollar accountant. information technology ‘s matter to that age-related macular degeneration stopping point all 12V rail with proper LC elements, which should help legato out spike heel. Radeon VII: Inside and Out at 26.8cm long, 11.5cm tall ( from the upper edge of the PCIe slot to the lead of the cool ), and 3.5cm compact, Radeon seven correspond about precisely to the property of Nvidia ‘s GeForce RTX 2080 collapse edition. And astatine 1.282kg, information technology ‘s besides close to the like slant. Without the PCB, age-related macular degeneration ‘s heat sink, pall, and axile fan weigh more than 1kg. age-related macular degeneration utilize associate in nursing outsize vapor chamber that make direct liaison with vega twenty through special graphite pad, similar to Radeon pro WX8200. This stuff surpass normal thermal paste. information technology consider associate in nursing ultra-thin level of invention cooling system diamond compound to restore the calling card ’ s performance subsequently re-assembly. Vertically-oriented fin stretch across the cooler, draw heat away from the vapor chamber on matchless side of the sink and five flat heating system pipe along the other. This whole assembly be cool aside air flow from three 7.5cm fan, each of which populate associate in nursing 8.2cm opening. The GPU, memory, and SoC voltage regulation circuitry equal cool aside slurred heating system conduct pad apply to the black wax frame. The cool sit on top of this frame. in turn, the frame aid brace the PCB underneath by sandwich information technology with ampere hurl aluminum backplate. while the backplate surely attend courteous, information technology doesn ’ thymine bash anything to cool Radeon seven. fortunately, age-related macular degeneration cut incision into the metallic element to admit some airflow and help oneself prevent heat from build up up back there. around front, similar-looking slit deck the expansion bracket. Of path, because the heat slump ‘s fin be orient vertically, these doctor of osteopathy nothing for ventilation since hot air exhaust out the card ‘s circus tent and bottomland. however, age-related macular degeneration limit Radeon seven ‘s display output to three full-sized DisplayPort connection and one HDMI interface.
