Note: Some of AMD’s motherboard partners have begun pushing the latest AGESA 1.0.8.0 BIOS firmware, and it has been confirmed that the next-generation APU, codenamed Phoenix, is the first processor of the AM5 platform.

Crash Test found that the AM5 APU has a different CPU ID than the original Phoenix APU, with a CPU ID of “00A70F52” for the Phoenix Refresh chip.

The forum member also reports that the Phoenix 2 APU is numbered “00A70F80,” which is different from the number used by the original Phoenix APU’s “00A70F41.”

This indicates that AMD may not adopt the first-generation design of only one architecture IP, but will use a hybrid Phoenix core configuration on the desktop AM5 platform, mixing Zen 4 and Zen 4C cores, which can provide more efficient in the same power consumption/performance range. experience.

So far, these chips have only appeared in mainstream laptops, and the Ryzen 7000 APU could be AMD’s first hybrid-core desktop chip.

The upcoming product is expected to target OEMs and SIs (system integrators) and support up to 96 Zen4 cores, up to 128 PCIe Gen5 lanes, and DDR5 compatibility.

The AMD Ryzen Threadripper PRO 7000 workstation CPU series, codenamed Storm Peak, is highly anticipated. More than 1.5 years have passed since the launch of the previous generation PRO 5000. The new processor will once again be positioned in the high-end workstation field.

According to the previously leaked information, the AMD Threadripper PRO 7000 series is expected to have five models, including 96-core 7995WX, 64-core 7985WX, 32-core 7975WX, 16-core 7955WX and 12-core 7945WX. The maximum TDP of all chips Rated at 350W.

As shown in the picture above, notebooks equipped with Ryzen 7040 and 7045 series mobile processors will be equipped with the latest orange stickers, while Ryzen 7020, 7030 and 7035 series processors will use the old stickers.

AMD changed the naming rules on the Ryzen 7000 mobile processor. The latest Zen4 architecture processors are named 7040 and 7045 series, and the old Zen2, Zen3, and Zen3+ processors are replaced with 7000 series vests. , named 7020, 7030 and 7035 series respectively.

As shown in the figure above, there are 22 models of AMD Ryzen 7000 mobile processors, more than half of which are not the latest Zen4 architecture.

Beginning in April, notebooks equipped with Ryzen 7040HS series processors will be launched, and then thin and light notebooks equipped with 7040U series will also be launched. Consumers who want to buy notebooks with AMD’s latest architecture processors can look for orange stickers.

Judging from the Cinebench R23 test results he gave, the processor finally scored 16854 points, which is about 25% faster than the Ryzen 7 6800H “Rembrandt” and faster than the fastest Rembrandt flagship processor Ryzen 9 6980HX About 15%, also stronger than the 13th generation Core i5 and 12th generation i7, but the single-core performance is still unknown.

Let me briefly mention the parameters here. The Ryzen 7 7840HS adopts the latest Zen4 architecture, based on the latest TSMC 4nm process, 8 cores and 16 threads design, equipped with 40MB cache, the base frequency is 3.8 GHz, and the highest frequency can reach 5.1GHz. At the same time, it integrates Brand new Radeon 780M core display.

It’s worth mentioning that if you need more cores and cache, you should wait for something like the AMD Ryzen 7045 in the Dragon Range lineup, which offers 16 cores, 32 threads and stronger cache performance.

The Ryzen 7 7840HS retains the same 35-54W TDP design as other Phoenix processors, but with impressive performance, this APU is expected to arrive later this quarter, and there should be plenty of laptops to choose from.

As you can see above, the PassMark score chart was originally topped by the previous generation 64-core Xiaolong EPYC 7773X, which has since been replaced by the Threadripper 64-core Threadripper Pro 5995WX. The latest winner, the EPYC 9654, now has 96 cores and 192 threads and is 20% ahead of second place.

AMD’s fourth-generation EPYC processors include 14 models ranging from 16 to 96 cores, all with the Zen4 architecture, and also support DDR5 memory and PCIe Gen 5 storage with CXL1.1+ memory expansion.

AMD says 4th generation AMD EPYC processors deliver a 2.8x performance increase while consuming 54% less power, building on its predecessor’s 300+ world records and supported by a complete software and hardware ecosystem spanning a wide range of workloads including database, virtualization, AI/ML, HPC and other scenarios.

According to reports, the “Phenix Point” series has two versions, PHX and PHX2, both of which are TSMC’s N4 process. The former has a maximum of 8-core Zen4 CPU + 12CU RDNA3 core display, 15-35W+ power consumption, and the latter has a maximum of 2 Zen4 + 4 Zen4C CPU, up to 4CU RNDA3 core display, 15-28W power consumption. Previous news said that the 128-core EPYC Bergamo will use Zen4C, a high-density multi-threaded architecture customized by AMD for cloud-native applications. Zen4C may be AMD’s small core.

In terms of naming, the R7 7840U is an 8-core Zen4 + 12CU core display, and the R7 7740U is a 2 Zen4 + 4 Zen4C + 4CU core display.

AMD will hold a CES conference on the 5th of next month, at which time the lineup of the Ryzen 7000 series mobile processors will be announced. This year’s Ryzen 7000 series mobile processors can be described as the generation with the most products. In addition to the latest Zen4 architecture new products, there are also vest models such as Zen3 and Zen3+.

AMD’s Ryzen 7X45HX series processors used in high-end gaming notebooks are transplanted from the Ryzen 7000 desktop, and the Ryzen 9 7845HX should be the low-frequency version of the R9 7900.

According to previous revelations, the AMD Zen4 architecture HX series will have the following four models, with up to 16 cores and 32 threads, a core display of 2CU, a TDP of 55W, and a maximum of 140W.

R9 7945HX 16c 2CU

R9 7845HX 12c 2CU

R7 7745HX 8c 2 CU

R5 7645HX 6c 2 CU

The AMD Zen4 architecture HX series will be benchmarked against Intel’s 13th generation Core HX series processors. This series of processors is also transplanted from the desktop. According to reports, the flagship model i9-13980HX is 8 large cores + 16 small cores, and the highest turbo frequency can reach 5.6. GHz.

The AMD CES conference will start on January 5th.

The post AMD Ryzen 9 7845HX high-end gaming processor appears: 12 cores and 24 threads appeared first on TechGoing.

Notably, the new version reintroduces a “Precision Boost C-State Limiter” that prevents CPU cores from being boosted above 5.50GHz when more than 4 cores are active (heavy load operation).

From SkatterBencher’s demo, the performance of high-end AMD Ryzen 7000 series desktop processors may be affected to a certain extent, but the impact is very limited.

▲ NopBench is a program developed by ElmorLabs that calculates the maximum frequency that can be obtained with the workload of the CPU cores (from 1 to n threads).

NopBench measures the number of NOP instructions that can be processed per second with the help of NOP instructions. To make NOP throughput comparable between processors of different microarchitectures, it also uses an architecture-specific factor, which is equal to 2.5 for “Raphael”.

By comparing the NOP throughput of Ryzen 9 7950X processors tested with AGESA 1.0.0.2 through 1.0.0.3 (ASUS ROG Crosshair X670E Extreme BIOS versions 0611 and 0705), SkatterBench concludes that

In the original 0046 or 0611 BIOS versions, the Ryzen 9 7950X processor can reach around 5.7GHz on all 16 cores, and when upgraded to the 0705 BIOS version based on the AM5 AGESA 1.0.0.3 microcode, the maximum frequency is only between 5.4GHz and 5.5GHz.

SkatterBencher concludes with six points, which are

Enabling C-State is the preferred option, originally because it provides higher performance for AGESA 1.0.0.2/1.0.0.3.

AGESA 1.0.0.3 microcode reintroduces the “Precision Boost C-State Limiter”, which was not present on the first motherboard and BIOS releases.

When more than 4 cores are active, the processor frequency is only up to 5.5GHz, which means that some Ryzen 7000 series processors may experience performance loss.

On motherboards with this option, simply enable “Medium Load Boostit” to bypass the limitation.

On motherboards without this option, asynchronous eclk provides the only viable overclocking strategy to get the processor frequency above 5.5GHz.

The actual performance limits imposed by the “Precision Boost C-State Limiter” are small, as users need at least one processor with multiple cores capable of running above 5.5GHz, and in fact most workloads are likely to trigger other limits, thus limiting the processor’s operating frequency. In fact, most workloads are likely to trigger other limits, thus limiting the processor operating frequency.+
