https://www.anandtech.com/show/16214/amd-zen-3-ryzen-deep-dive-review-5950x-5...This is a massive Anand Tech review of the first Ryzen 3 "x" processors from AMD that were promised to arrive around Nov. 5th after the Ryzen 3 processors and the "x" grade was announced in early October. It is now Nov. 6th and the Anand Tech review is here as promised. The entire review is 30 web pages long and it is an exhaustive, exhaustive review to say the least (and if you are an Intel fan, the entire thing is totally, totally painful and demoralizing for you to read it all). There is a scroll bar up at the top of each page on this review, as each set of the 30 sets of web pages covers just one of thirty topics or tests ...... So, the angry green She Hulk did catch up with Intel early on in the review and she simply wadded him up so tightly so he could fit into the standard Intel octagonal box along with a suitable brown stinky Intel Marketing crown that was freshly laid down on his bleeding scalpless skull personally by the angry green She Hulk.
As last glimpsed, "Intel inside the box" was still struggling a tiny bit, still twitching and weakly squeaking a tiny bit underneath his current stinky brown crown as She Hulk tucked the last flap of the octagonal box flap into place and then she carefully installed the little "Intel Inside" sticker seal over the now security sealed box flap of the (still dripping from the bottom) Intel octagonal container .......Conclusion: AMD Has Indeed Ryzen To The TopComing out the other end of this review, it’s hard to believe the extent to which some of AMD’s performance numbers have grown in the last five years. Even within the Ryzen family, we can pinpoint the leaps and bounds by which AMD is now the market leader in pure x86 performance.
Let’s start with some headline numbers.
+19% IPC Gain is Confirmed at 24%
AMD quoted to us a raw IPC gain from Zen2 to Zen3 of +19%. AMD measured this with 25 workloads and both processors at 4.0 GHz, running DDR4-3600 memory. By comparison, we test with industry standard benchmarks at rated clock speeds and JEDEC supported memory, and we were able to accurately achieve that +19% number.
Compounding the generation-on-generation gains from a pre-Ryzen era, we’re seeing +114% IPC improvements, and if we look from the original Zen to Zen3, it is a ~41% gain.
In real world benchmarks, we saw an average +24% performance gain, showcasing both the increase in IPC and frequency uplift that the Ryzen 5000 parts have.
5.0 GHz Achieved on Ryzen
Turbo frequencies are often setup dependent, and because AMD uses a combination of listed turbo frequency and opportunistic boosting, the exact turbo frequency can be hard to nail down. For the top-tier Ryzen 9 5950X, AMD lists the turbo frequency as 4900 MHz for single core loading, however in very standard conditions, we were able to pass that to 5050 MHz. Diving deeper into the AGESA, this processor actually has a ‘maximum frequency’ setting of 5025 MHz. All of our Ryzen 5000 series processors offered +50-150 MHz above the listed turbo showcasing that these parts still have some headroom.
Overall Impressions of Zen 3 and Ryzen 5000
One of the exciting things about probing a new core is finding out all the little quirks and improvements that they don’t tell you about. It’s been interesting finding out how this core was put together, both from our findings and discussions AMD’s engineers.
Moving to an 8-core CCX for this generation was a no-brainer, with an easy up-tick in performance. However it is the changes in the execution units and load/store were a lot of the magic happens – increasing to peak 3 loads/cycle and 2 stores/cycle, splitting out some of the ALU/AGU work, finer grained transitions from decoder/op-cache to the micro-op queue, and pre-fetchers with more bandwidth all help to that. A lot of the instruction improvements, such as lower latency FMA and faster DIV/IDIV is going to scale well as we move into the enterprise and EPYC processors.
With AMD taking the performance crown in almost areas it is competing in, attention now rolls over to price. Having $300 as an entry level for this tier is going to sting a lot of users who would rather spend $200 or less – despite AMD having nine out of ten of Amazon’s best sellers, only two of those parts are $300 and up. There’s going to be an early adopters tax as well – one could argue that moving into Q1, when AMD is enabling 400-series motherboards, might be a better inception point for a lot of users.
Having said that, with Intel set to launch Rocket Lake at the end of Q1 next year with 8 cores, this sub-$300 market is going to be ripe for any AMD Zen3 APU to come in and take that price bracket. Remember, AMD never launched Zen2 APUs into the consumer market, which might indicate a fast follow-on with Zen3. Watch this space – a monolithic Zen3 APU is going to be exciting.
AMD Ryzen 5000 Series Processors
Ryzen 9 5950X 16c/32t 3400 4900 64 MB 105 W $799 Ryzen 9 5900X 12c/24t 3700 4800 64 MB 105 W $549 Ryzen 7 5800X 8c/16t 3800 4700 32 MB 105 W $449 Ryzen 5 5600X 6c/12t 3700 4600 32 MB 65 W $299*
All things considered, we’re really impressed with what AMD has achieved here. After the disillusionment of years of weaker generation-on-generation performance uplifts from the competition, AMD set a goal to beat the average ~7% IPC year-on-year gain. With +19% IPC on Zen3, Intel has no product to match AMD right now - not even Tiger Lake at 4.8 GHz - and Intel has lost that single-threaded crown.
AS SUCH, AMD now wins the total brand crown for GAMING and for content creation as AMD sweeps the top 4 spots before an Intel processor even gets a listing in the rankings. Note please that AMD can easily break 5.0 ghz at only 105 watts of power, while Intel takes 140 watts or more to do the same upper level ghz speeds. Also note that this is all done at a bog standard TSMC 7nm lithography level. Also note that with the brand new just breaking AMD 5nm chiplets that are currently being run off at TSMC there will be BRAND NEW WAVES OF AMD PROGRESS TO FOLLOW QUICKLY AFTER THIS ONE, each new wave lapping up significantly higher on the beach and lapping out fairly quickly too. =================================================== Look for new ever higher AMD progress waves to hit the beach scheduled roughly every six months apart until every Intel marketing sandcastle is completely leveled and totally washed away (this will take place easily inside the next calendar year no less) ....... TO PROTECT THEIR CASTLE WALLS from scaling ladders, Intel has added more height to the speed crenellations, raising them from 5.0 to up to 5.6 ghz tall ....... at 160 watts of power consumed and even bigger heat pipe cooling fins and fans to match. This makes no difference to the AMD groundswell waves that are coming in, waves that plow into the Intel built castle walls down low, eroding sand from underneath their foundations, not by going over the tops of Intel's best hyper stacking over voltage efforts.
