AMD Ryzen 7 PRO 6850U "Rembrandt" Linux Laptop Benchmarks​

Here is the first of several articles looking at the AMD Ryzen 7 PRO 6850U Linux performance using a Lenovo ThinkPad X13 Gen3.
The Ryzen 7 PRO 6850U is 8 cores / 16 threads like the prior Cezanne Ryzen 7 PRO 5850U but now with a 2.7GHz base clock and 4.7GHz maximum boost clock compared to 1.9GHz base clock and 4.4GHz boost clock with the prior generation part. The Ryzen 7 PRO 6850U has a 15 to 28 Watt configurable TDP and this Zen 3+ processor is manufactured on a TSMC 6nm FinFET process compared to TSMC 7nm FinFET with the former Cezanne Zen 3 models.

The Ryzen 7 PRO 6850U also now supports DDR4-4800 / LPDDR5-6400 memory compared to DDR4/LPDDR4 with the Cezanne models. Arguably most exciting with the Ryzen 7 PRO 6850U is the Radeon 680M graphics that are based on RDNA2 rather than the long used Radeon Vega graphics with prior AMD APUs.

My Ryzen 7 PRO 6850U Linux testing has been happening using a Lenovo ThinkPad X13 Gen3 (21CM0001US) that features 16GB of LPDDR5-6400 (soldered) memory, 512GB NVMe PCIe 4.0 SSD, 13.3-inch 1920 x 1200 IPS 300 nit display, and makes use of the integrated Radeon 680M graphics. It's a nice laptop and all basic functionality works out under Linux while more on the laptop itself under Linux will be talked about in the forthcoming ThinkPad X13 Gen 3 Linux review.

The laptops/processors used for this initial round of AMD Rembrandt Linux benchmarking included:


- Core i7 8565U - Dell XPS 13 9380
- Core i7 1065G7 - Dell XPS 13 7390
- Core i7 1185G7 - Dell XPS 13 9310
- Core i7 1280P - MSI MS-14C6
- Core i7 1280P - MSI MS-14C6 + 5.19-rc7
- Ryzen 7 4700U - Lenovo LNVNB161216
- Ryzen 5 5500U - TUXEDO Aura 15 Gen2
- Ryzen 7 PRO 5850U - HP Dev One
- Ryzen 9 5900HX - ASUS G513QY
- Ryzen 7 PRO 6850U - ThinkPad X13 Gen3
- Ryzen 7 PRO 6850U - ThinkPad X13 Gen3 + 5.19-rc7

All of these laptops were tested on Ubuntu 22.04 LTS using the Linux 5.18 kernel.

Due to seeing improved power efficiency for Alder Lake P with Linux 5.19, the Core i7 1280P was tested both using Linux 5.18 like the other laptops and again with Linux 5.19-rc7. So, similarly, the Ryzen 7 PRO 6850U was tested also with Linux 5.18 and 5.19-rc7.

Across both OpenGL and Vulkan workloads the Radeon 680M graphics were performing very well on the latest open-source drivers. For those interested in the Radeon 680M potential for Linux gaming, a follow-up article will look much more closely at the 680M gaming performance...

It's with the CPU power consumption where the Ryzen 7 PRO 6850U becomes much more compelling. Above is a look at the CPU power consumption over the entire span of benchmarks conducted. The Ryzen 7 PRO 6850U with the Linux 5.18 kernel had a 18.4 Watt average (or 16.6 Watt average with Linux 5.19 Git) while the Ryzen 7 PRO 5850U average on Linux 5.18 was up at 21.96 Watts. The peak power consumption of the 5850U during testing was 47 Watts compared to 41 Watts with the 6850U or even down to 35 Watts with Linux 5.19 Meanwhile the Core i7 1280P had a 35 Watt average on Linux 5.18 and a peak of 107 Watts... It's with Linux 5.19 Git where the Intel Idle driver support is there that Alder Lake looks better in the power efficiency department but still behind the Zen 3/3+ parts tested. On Linux 5.19 the i7-1280P had a 30 Watt average and a peak of 75 Watts.
Screenshot-2022-07-22-at-01-39-48-AMD-Ryzen-7-PRO-6850-U-Rembrandt-Linux-Laptop-Benchmarks.png

The Ryzen 7 PRO 6850U CPU core temperature in the ThinkPad X13 Gen3 during the entire span of benchmarks was 69 degrees compared to the 5850U having an average of 81 degrees. The Core i7 1280P in the MSI Evo notebook had an average core temperature of about 67 degrees.

The AMD Ryzen 7 PRO 6850U in most benchmarks was only slightly faster than the Ryzen 7 PRO 5850U, but its power efficiency with Zen 3+ tended to be much better. It was a nice improvement in performance-per-Watt with Rembrandt and further extends the AMD power efficiency wins over Intel Alder Lake P.

Deixo este gráfico aqui, dessa review. Olhar especialmente para o 6850U e o 1280P.

Há sempre o contra de, comparações entre portáteis de marcas/modelos ser muito complicado.
 
Bom preço é sempre algo relativo. Mas tendo em conta que a concorrência até tem subido os preços, para quem precisar de um octacore, parecem-me ser excelentes opções por esse preço.

Duvido que os Zen3 tenham muita margem para descerem mais do que isso mesmo saindo os zen4. O unico que vejo que poderá ter descida acentuada é mesmo o 5800X3D, mas só quando sairem zen4 com vcache
 
Se precisas mesmo dum CPU para produtividade vais vale logo ires para o 5900x.
Pelo menos ficas com 12 cores.
Pagar mais de 100€ de premium por 2 extra cores que não vão fazer diferença na grande maioria dos casos não me parece sábio.
Por mais 200€ no 5900x levas logo mais 6 cores que vão realmente fazer diferença em produtividade.

Isto a comparar com o preço de 189 do 5600.
 
Foste tu que inicialmente pediste a sugestão no tópico.
Se se o 2600 te serviu até agora, não vejo a razão dum 5600 não servir, não vão ser os 2 extra cores por +100€ que de vão dar muita mais performance, dai a sugestão do 5900x que é realmente virado para produtividade e os 6 extra cores já se vao fazer sentir.
Vão te tentar dar a melhor sugestão no contexto, agora podes fazer upgrade para o 5800x, mas vais ter um cpu mais quente com pouco ganho em performance. Pelos menos o 5900x é quente mas tens 12 cores.

Q2 2022 Financial Summary
  • Gross margin was 46%, a decrease of 2 percentage points year-over-year, primarily due to amortization of intangible assets associated with the Xilinx acquisition. Non-GAAP gross margin was 54%, an increase of 6 percentage points year-over-year, primarily driven by higher Data Center and Embedded segment revenue.
  • Operating income was $526 million, or 8% of revenue, compared to $831 million or 22% a year ago primarily due to amortization of intangible assets associated with the Xilinx acquisition. Record non-GAAP operating income was $2.0 billion, or 30% of revenue, up from $924 million or 24% a year ago primarily driven by higher revenue and gross profit.
  • Net income was $447 million compared to $710 million a year ago primarily due to lower operating income. Record non-GAAP net income was $1.7 billion, up from $778 million a year ago primarily driven by higher operating income.
  • Diluted earnings per share was $0.27 compared to $0.58 a year ago primarily due to lower net income and a higher share count as a result of the Xilinx acquisition. Non-GAAP diluted earnings per share was $1.05 compared to $0.63 a year ago primarily driven by higher net income.
  • Cash, cash equivalents and short-term investments were $6.0 billion at the end of the quarter and debt was $2.8 billion. AMD repurchased $920 million of common stock during the quarter.
  • Cash from operations was a record $1.04 billion in the quarter, compared to $952 million a year ago. Free cash flow was $906 million in the quarter compared to $888 million a year ago.
  • Goodwill and acquisition-related intangible assets associated with the acquisitions of Xilinx and Pensando were $50.4 billion.


  • Data Center segment revenue was $1.5 billion, up 83% year-over-year driven by strong sales of EPYC™ server processors. Operating income was $472 million, or 32% of revenue, compared to $204 million or 25% a year ago. Operating income improvement was primarily driven by higher revenue, partially offset by higher operating expenses
Data Center segment includes server CPUs, data center GPUs, Pensando and Xilinx data center products.
  • Client segment revenue was $2.2 billion, up 25% year-over-year driven by Ryzen™ mobile processor sales. Client processor ASP increased year-over-year driven by a richer mix of Ryzen mobile processor sales. Operating income was $676 million, or 32% of revenue, compared to $538 million or 31% a year ago. Operating income improvement was primarily driven by higher revenue, partially offset by higher operating expenses.
Client segment includes desktop and notebook PC processors and chipsets.
  • Gaming segment revenue was $1.7 billion, up 32% year-over-year driven by higher semi-custom product sales, partially offset by a decline in gaming graphics revenue. Operating income was $187 million, or 11% of revenue, compared to $175 million or 14% a year ago. Operating income improvement was primarily driven by higher revenue, partially offset by higher operating expenses. Operating margin was lower primarily due to lower graphics revenue and higher operating expenses.
Gaming segment includes discrete graphics processors and semi-custom game console products.
  • Embedded segment revenue was $1.3 billion, up 2,228% year-over-year driven by the inclusion of Xilinx embedded revenue. Operating income was $641 million, or 51% of revenue, compared to $6 million or 11% a year ago. Operating income and margin improvement was primarily driven by the inclusion of Xilinx revenue.
Embedded segment includes AMD and Xilinx embedded products.
All Other operating loss was $1.5 billion as compared to $92 million a year ago due to amortization of intangible assets largely associated with the Xilinx acquisition.

Ou seja, aco contrario da Intel, deram lucro em todos os segmentos e cortaram nos dividendos para inverstir.
Parece-me que andam a ter melhores decisões de negócios que nos lados azuis...

AMD Financials Q2 and Analyst Q&A​


https%3A%2F%2Fbucketeer-e05bbc84-baa3-437e-9518-adb32be77984.s3.amazonaws.com%2Fpublic%2Fimages%2Fd0b45ba9-1bb2-4646-85c4-83c9ed460919_2744x1803.png


Takeaways from the AMD Q2 Financial call, in no particular order:
  • 5nm Zen 4 launch in Q3, Ryzen (desktop) and Genoa (server)
  • RDNA 3 launch in Q4
  • AMD is still supply constrained, however more is coming online through 2H. This is largely why AMD can post growth predictions.
  • AMD is about 40-42% weighted in the datacenter, tending to 50/50
  • Whereas Intel showcased a 30% YTD revenue drop in notebook last week, AMD is saying that client (including notebook) increased 25% QoQ, driven by Ryzen Mobile sales. I asked for a breakdown of units vs ASP mix, especially as the PC market is trending down around 15% according to AMD. I was told the statement of ‘sales’ was purely about revenue, and they weren’t going to break out any more details on that
  • Console sales will remain strong through Q3, projecting to a record year for semicustom, which offsets the gaming GPU market being weak. No new semi-custom customers, still mostly Sony/Microsoft with a small amount from Steam Deck and Magic Leap.
  • Embedded, which now includes Xilinx, is up 2228% YoY. That’s not a typo, that’s just because it now includes Xilinx. That being said, AMD has improved Xilinx’s supply chain to increase margins and opportunity. Xilinx revenue grew 20% sequentially (so far).
  • AMD’s visibility into EPYC demand is strong, with cloud customers already profiling Genoa and demanding it ASAP. AMD is set to focus on the high volume cloud and high volume enterprise SKUs first. They expect a long overlap between Milan (current gen) and Genoa (next gen), especially as cloud and enterprise offerings develop. Some enterprise/OEM offerings are limited today due to lack of components to complete systems (e.g. a Dell server might be limited by a lack of ethernet cards to sell those systems), hence the build out and growth as those markets get better as well
  • AMD initiated $920m of stock buybacks in Q2, making $2.8B year-to-date. Another $7.4 billion are still authorized, although no time limit
    • Some people ask why AMD is doing stock buy backs instead of reinvesting in supply or R&D - AMD is already going full bore on R&D, with lots of hiring, which takes time. It’s the time that’s the killer - you can’t simply start a chip design product and pluck 500 people for it off the street. On a lot of projects, more people won’t help either, it’s a case of going through the motions (such as having a child can’t be accelerated, or playing a piece of music as intended). During that time, you don’t sit on money, you return it to investors through buybacks. This gives the company/main shareholders more leverage and control for sure, but also raises share price which in turn can be used as leverage for cheap debt which is sometimes more favourable.
  • With Xilinx in the mix, AMD’s market share numbers are a little off kilter. In the Q&A, one financial analyst said it’s now in the mid 20% range, which would be double the low 10% numbers we saw a few Q ago. It’s gone up sure, but it’s still a slow increase comparing apples to apples.
  • AMD is still insulated from a lot of the industry slow down. The markets it plays in (DC, cloud, enterprise, commercial) are more TCO focused than chip price focused. Even in consumer markets, AMD is focused on the high-end which is more about product than price (although is still price sensitive). The super price sensitive markets, such as government and embedded, AMD is shielded from that as they have very little business there. AMD doesn’t have to engage there at this time as they’re spending capacity on high revenue parts and they’re selling like hot cakes. Hence the record revenues.
  • It was noted that even though revenue grew, and with the Xilinx acquisition, the free cash flow (FCF) was only up slightly. AMD said that this is due to a number of factors - investment in working capital, the tax rate going up from 3% to 10% with large Q2 payments due to cycles, shipment times also affect FCF with supply, and also AMD’s investments in capacity involve a good amount of up-front pre-payment to suppliers (read, TSMC and OSATs).
  • Non-GAAP ***** were 54%, but GAAP ***** were 46%. That’s a big difference

Advantech has announced the AIMB-522 industrial Micro-ATX motherboard with AMD Ryzen Embedded 5000 Series Zen3 processors for AI image processing in automation and surveillance applications.
JaK0mzj.jpg

I had never heard about “Ryzen Embedded 5000 Series” processors, but that motherboard comes with a choice of new SKUs such as the 12-core Ryzen 5950E, the 10-core Ryzen 5900E, the 8-core Ryzen 5800E, and the 6-core Ryzen 5600E, as well as existing Ryzen 5000 desktop processors.
Processor:
  • Ryzen 5950E 12-core processor @ up to 3.4 GHz with 64MB L3 cache; TDP: 105W
  • Ryzen 5900E 10-core processor @ up to 3.7 GHz with 64MB L3 cache; TDP: 105W
  • Ryzen 5800E 8-core processor @ up to 3.7 GHz with 32MB L3 cache; TDP: 100W
  • Ryzen 5600E 6-core processor @ up to 3.6 GHz with 32MB L3 cache; TDP: 65W
Ryzens Embedded em Socket e Ryzens com 10 Cores acho que são uma novidade. Um Ryzen com 10 Cores, no mercado consumidor, talvez tivesse sido uma boa proposta.
 
Seria interessante sim, pegar 2 CCD e tirar 3 cores ruins em cada.

Só acho estranho o naming
- Devia ser tipo 5850E e 5900E, deixar o 5950E para um 16C
- O prefixo "E" devia ser usado mais para "energy efficient" ihmo, mais valia usar um "B" para emBedded
