Only yesterday we wrote about Intel’s cunning, allowed in the official comparison of the performance of the Core i9-12900K and Ryzen 9 5950X, and today there are new details about CPU Alder Lake, which also directly relate to performance. But if yesterday it seemed that in its normal state the Core i9-12900K, if it does not exceed the performance of the current AMD flagship, then at least will be at the same level with it, then, according to new data, the Core i9-12900K, equipped with the “wrong” motherboard, will run 30% slower than if used with a mid-range or high-end motherboard. That is, when using a bundle “Aler Lake + cheap motherboard” there is no question of any parity with the Ryzen 9 5950X. But what is the problem?
As it turned out during real tests, Alder Lake is very demanding on the motherboard power subsystem. Inexpensive solutions cannot deliver 135W of power for the long time required for optimal performance of the Alder Lake CPU. Recall that the Power Limit 1 of these CPUs is 125 W, but they naturally consume more under load.
Power shortages result in lower frequencies in Boost mode. As a result, the performance of the Core i9-12900K drops by 25-30%, the Core i7-12700K – by 21-25%, the Core i5-12600K – by 7-9%. The experiment showed that for normal operation of top-end Alder Lake CPUs, a motherboard with a power subsystem built according to the “10 + 1 phase” scheme, producing a current of 50 A with DrMOS integrated circuits, is required. Everything is the same, but with the “6 + 1 phase” scheme, it is already a bottleneck for system performance.
Interestingly, the Asus motherboards based on the Intel Z690 chipset, which we wrote about at the weekend, do not have a single model with a power subsystem of less than 11 phases. But other manufacturers will have such solutions. So when choosing a motherboard for CPU Alder Lake, you need to look not only at the type of supported RAM, but also pay close attention to the power subsystem.
The cooling system for Palit GeForce RTX 2060 Dual series graphics cards with 12 GB of memory includes two 90 mm fans
Palit Microsystems, which calls itself the largest partner of Nvidia in the production of video cards, introduced the GeForce RTX 2060 Dual and GeForce RTX 2060 Dual OC models with 12 GB of memory. As you know, these are improved versions of the well-known model built on the Nvidia Turing architecture. They differ from the original version in the increased number of CUDA cores and doubled the amount of memory. The cards support Nvidia DLSS, Nvidia Reflex, real-time ray tracing and many other modern technologies. Contrary to the letters of the OS in the name, usually indicating factory overclocking, in both cases the base frequency is 1470 MHz, the increased one is 1650 MHz. GDDR6 memory communicates with the GPU over a 192-bit bus, transferring data on each line at 14 Gbps.
The cooling system design for the new graphics cards includes two 90mm fans. The mounting plate has a Dual-Link DVI-D, HDMI 2.0b and DP1.4a video outputs connector. The card measures 235 x 115 x 40 mm and occupies two slots in the PC case. It consumes 184 watts. It has one 8-pin PCIe auxiliary power connector.
Zotac introduced the GeForce RTX 2060 graphics card with 12 GB of memory
Like Nvidia’s other graphics card partners, Zotac has unveiled the GeForce RTX 2060 with 12GB of memory. According to the source, Nvidia has “called from the stock” the GeForce RTX 2060 model, increasing the number of CUDA cores and doubling the memory from the previous 6 to 12 GB to meet AMD’s recently unveiled Radeon RX 6600.
The Turing graphics architecture at the heart of the GeForce RTX 2060 is still modern as it offers full DirectX 12 Ultimate support. The GPU configuration includes 2,176 CUDA cores, 34 RT cores, and 272 Tensor cores. The GDDR6 memory is connected to a 192-bit bus.
As for the Zotac board, this is a fairly simple and compact model with a cooling system that includes an aluminum heatsink and a couple of fans. The card is powered by a single 8-pin PCIe power connector. No pricing information yet.
There is confusion in the ranks of the new Intel CPUs: the processor with fewer cores is older than the model with more cores. It’s all about the cores themselves
The heterogeneous structure of Intel processors, when there are fast large and small energy efficient cores, in theory can lead to situations where a processor with fewer cores will be better than a model with a larger one. Judging by the latest data, this situation will take place in Intel’s lineup.
The specifications of the mobile CPU Core i5-12650H show that it has fewer cores than the younger Core i5-12500H. But at the same time, the Core i5-12650H received its number for a reason.
Yes, it has 10 cores versus 12 cores for the younger model. But the ratio is important. While the Core i5-12500H has 4 large cores and 8 small cores, the Core i5-12650H has 6 large and 4 small cores. And for most, if not all, this configuration will be faster.
Judging by what we now know about future Alder Lake, there will be no such confusion in the desktop segment, but still we need to wait for the official announcement of all these processors, which will take place early next year.
