Intel's chips are competitively priced, but PCIe 5.0 and DDR5 are also significant cost-adders for motherboards. All signs point to DDR5 kits being expensive in the early days, so it's good that some motherboards support the more affordable DDR4. Coming Zen3D, interest in Alder Lake will drop even more (it already has worse sales than predicted/wanted). helper800 said:I can respect your opinion, but I disagree. In my opinion companies all do what they can to stay as profitable as then can. Consumer "goodwill" is just another currency these large multinational companies spend and receive for various conduct. AMD currently has a decent amount of goodwill, however, they spent a major chunk of it by not releasing a 5600, 5300, 5700 / 5800 while also increasing prices by 50 dollars across the board. They did this for money and they knew they could get away with it because they had garnered enough consumer goodwill.There is no innocent company, AMD included. I also don't like those same things you stated about AMD that they did recently, but compared to nvidia and intel (on topic), the amount of scummy or s * things AMD did is almost meaningless.
Thread Director is informed by a new microcontroller on the CPU itself, which will feed Windows 11 more detailed hardware telemetry about the current status of the chip and its cores, versus older releases in Intel's desktop line. Information that was previously left a mystery to Windows—think aspects like thermals, power settings, and which threads can take more instructions—is now communicated to the scheduler in microseconds, leaving almost no impact and (in theory) adding considerable performance gains, depending on the workflow and the various kinds of overhead that can be leveraged. First up, CPU tests. We ran the various CPUs below (including the Alder Lake chips) under Windows 10, on appropriate testbeds built fresh for this generation of CPUs. (We also reran some of the tests on the Core i9-12900K under Windows 11 to get Thread Director into the mix.) There is a wide selection of DDR5 motherboards spread among the various motherboard makers' Z690 families, but it appears that you'll only find DDR4 support on lower-end Z690 boards. Also, unlike previous generations, no motherboard supports both DDR4 and DDR5, which is probably due to DDR5's much tighter signal integrity requirements and onboard power control circuitry. Intel's Thread Director is a hardware-based technology that assures threads are assigned to either the P or E cores in an optimized manner. This is the sleeper tech that enables the hybrid architecture.Alder Lake takes the lead over Ryzen in most workloads, but it isn't a slam dunk in every regard — we ran into several odd performance trends with Windows 10, and a few programs even refused to run correctly.We do expect those issues to be fixed sooner rather than later, though, as the industry adapts to the hybrid architecture. And while normally we'd take the rest of this section to talk about all the nuances of the results and what they could mean for Intel's new position in PC gamer's minds, there's just one problem we noted: The Core i9-12900K can't play every game. Italics intentional.
Alder Lake chips expose up to 16 lanes of PCIe 5.0 and an additional four lanes of PCIe 4.0 from the chip for M.2 storage.Those lanes are split into x16 or x8 for GPUs, or x4/x4 for storage slots. PCIe AICs (Add-In Cards) that support PCIe 5.0 M.2 SSDs (which don't exist yet) are already in the works. All models support up to DDR5-4800, LPDDR5-5200, DDR4-3200, or LPDDR4X-4266 memory, and 28 lanes of PCI Express 4.0/3.0.
All models support: MMX, SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, AVX, AVX2, AVX-512, FMA3, MPX, Enhanced Intel SpeedStep Technology (EIST), Intel 64, XD bit (an NX bit implementation), Intel VT-x, Intel VT-d, Turbo Boost, Hyper-threading, AES-NI, Intel TSX-NI, Smart Cache. We tested the CPUs here on their respective platforms in Windows 10 using a GeForce RTX 3080 Ti card. As you can see from our gaming runs above, things are actually quite close between the two processors, despite 12th Gen's ostensible platform and newness advantage. Between the two, the difference falls nearly within the margin of error for all tests aside from 3DMark, and that score is one that more accurately reflects the system advantage as a whole, rather than just the performance of the chip on its own.
Great Deal
