In the spring of 2020, Ampere introduced the 80-core ARM-based Altra processor. Recently, the processor was sent to thematic publications, and the first test results were not long in coming.
The processor is based on the ARM V8.2 + architecture and has up to 80 cores. The Arm CoreLink CMN-600 mesh bus is used to connect the cores. Kernels are supported by the cache system: 64 + 64 KB L2, 1 MB L2 and up to 32 MB L3.
Peripherals are connected via a PCIe 4.0 controller on 128 lanes. The two-socket version has 192 lines.
Unlike its counterparts, Ampere Altra has no multithreading. The developers refer to this as an advantage because the removal of the SMT lowers power consumption, which is extremely important for high-density systems.
The journalists received two-socket Mount Jade platforms, consisting of two 80-core Altra Q80-33 processors with a frequency of 3.3 GHz and a thermal package of 250 W. Each chipset has 512GB DDR4-3200 memory.
For comparison, the AMD EPYC 7742 64-core (SMT2, 225W) processor cost $ 6,950 and the 28-core Intel Xeon Platinum 8280 (SMT2, 205W) cost $ 10,009.
If we compare prices, the solution offered by Ampere is more attractive – the processor is priced at $ 4,050. The offer becomes even more attractive when you look at the characteristics of the chipset.
It should be noted that unlike most processors, for which “turbo mode” is exceeding a certain frequency, the Ampere Altra model always operates at the maximum declared frequencies, occasionally reducing this figure.
Altra was one of the leaders in the bandwidth test, demonstrating all the benefits of a flexible DRAM usage model.
In single-threaded tests, Altra Q80-33 showed results that are inferior only to the Intel Xeon Platinum 8280, beating in some tests AMD EPYC 7742.
In the multi-threaded test, the Altra processor became the clear leader. As we have already reported, the model almost always operates at maximum frequencies.
But in Java tests, things turned out to be worse. Firstly, the Altra lacks SMT, and secondly, the chipset software is imperfect. The lack of multithreading and the oversaturation of the internuclear mesh network also played a role.
The new processor also performed well when working with ray tracing.
The test authors said the Mount Jade system performed excellently. It offers users 160 efficient cores and low power consumption, as well as a pool of RAM up to 8 TB.

Up to 8 XE cores and 6 GB of memory: the first information about the Intel Arc Pro A50/A40 graphics cards appeared
The database of the SiSoftware Sandra test package has fresh data on the upcoming Arc A40 Pro and Arc A50 Pro graphics cards. These are graphics accelerators for workstations that are designed for engineering tasks.
The A50 Pro has a full ACM-G11 GPU with 8 Xe cores (128 execution units/1024 FP32 cores), while the A40 Pro is likely to get a stripped-down version of the chip. The clock frequency is 2.45 GHz.
Both cards have 6 GB GDDR6 memory, indicating a 96-bit memory bus. In this regard, both models are similar to the Arc A380 mobile card, which has almost the same configuration.
Thus, the company continues to prepare its entry-level products. When high-performance gaming and professional solutions based on the ACM-G10 GPU will appear, it is not reported. It is also not yet clear whether the Arc A40 Pro and Arc A50 Pro cards will be available in retail or whether they will appear only as part of workstations.
Earlier, Intel introduced its first gaming graphics card for $150.
Named the likely date of the announcement of the mobile processor Qualcomm Snapdragon 8 Gen 2
Qualcomm has updated its 2022 product launch roadmap. And there, among other things, they indicated the likely date for the announcement of the flagship Snapdragon 8 Gen 2 processor. It is expected to be shown on the first day of the Snapdragon Summit event, which will be held from November 14 to 17.
Qualcomm also announced the Snapdragon X70 5G modem that will be included with the Snapdragon 8 Gen 2. It is credited with download speeds of up to 10 Gbps, as well as new advanced features for working in fifth-generation networks.
The processor (SM8550) will be manufactured using TSMC’s 4nm process. It will use a three-cluster layout. The composition is expected to include one super-powerful Cortex X3 core, two productive Cortex-A720 and A710, as well as three energy-efficient Cortex-A510. An Adreno740 graphics accelerator is also expected.
It is assumed that the first smartphone based on the Snapdragon 8 Gen 2 processor will be Xiaomi 13, its presentation is expected before the end of 2022.
Are the recommended prices for modern video cards too high? Calculated how adapters are priced based on performance
Current generation video cards have been heavily overpriced almost all the time due to scarcity and demand from miners. Now the prices are getting back to normal, but how normal are the prices that are recommended? The source decided to evaluate how fair these prices are in terms of performance.
The source took the GeForce RTX 3070 as a conditional standard, which, according to our colleagues, is fairly priced if we take 4K resolution.
As you can see, there is an even more profitable graphics card – GeForce RTX 3060 Ti. That is, it offers more than its price of $400. As for the rest of Nvidia’s cards, most of them have not gone far from the standard, offering 90-94% price match. But all high cards are heavily overvalued. The same GeForce RTX 3090 Ti, according to such calculations, should cost only $ 814, and not $ 2,000 at all.
As far as AMD cards are concerned, only the Radeon RX 6800 and 6800 XT can be distinguished here, which are very close to 100%. Also, the Radeon RX 6700 XT has a rate of 92%. The rest of the cards are significantly more overpriced, although no model falls short of the RTX 3090 Ti in this indicator, simply because even the RX 6950 XT is almost half the price.
It is worth mentioning separately that the source only evaluated performance in games, so all calculations are rather arbitrary. They do not take into account the non-gaming capabilities of video cards, the same huge amount of memory in top GeForces, the complexity of GPU and PCB production, and so on.
