AM4 platforma je na zalazu karijere, tak da su ovi firško izdani modeli zadnji trzaji, a kaj se AM5 + DDR5 tiče, na kraju budu oba proizvođača isforsirala novi RAM standard.
Citiraj:
Intel is apparently already asking motherboard makers to avoid using DDR4 in combination with the upcoming 700-series chipsets and the only reason for this would be to speed up the transition to DDR5.

Kak god se okrene opet budu svi skupa zaradili na novim platformama, a korisnicima preostaju postojeća DDR4 rješenja da si iskombiniraju kaj im najbolje paše.

AMD Ryzen 7 5800X3D Review - The Magic of 3D V-Cache:kafa:
Citiraj:
AMD is taking a completely different approach with the Ryzen 7 5800X3D, instead of shooting for more MHz, they introduced a technological innovation that is almost as game-changing as the introduction of processor chiplets that enabled the tremendous success of Ryzen Zen 2 and Zen 3. The 3D V-Cache, as AMD calls their new innovation, is a silicon die that consists purely of cache memory, not compute cores or similar logic. A cache in computing is a fast piece of storage that sits in the data transfer path, and that stores pieces of data that are often used (hot data, where the heat represents frequency of access). If the cache is now able to fulfill a request for some data, then no full trip to the main memory is needed, which improves performance, because the cache runs a much greater speed and far better latency than the main memory on your motherboard ever could. A typical modern computer has 16 GB or 32 GB of memory, cache sizes are between 10 MB and 64 MB, so roughly a thousandth (!). On the Ryzen 7 5800X3D, the cache size is 96 MB, as opposed to 32 MB on the Ryzen 7 5800X. This 64 MB increase might not sound like much, even your phone can download that much data in a few seconds, it still has the potential to make a big difference.
It seems that games are an ideal workload for higher cache sizes, which is probably why AMD has been shipping their Ryzen processors with relatively large caches (compared to Intel), even though cache takes up a lot of silicon die area, which costs money. Averaged over our 10 games at the CPU-bottlenecked 720p resolution, the Ryzen 7 5800X3D can gain an impressive 10% in performance over its 5800X counterpart. This is enough to make it the fastest gaming CPU, right behind Intel Core i9-12900K and i9-12900KS. Considering that Intel's Alder Lake comes with a new and improved core architecture, runs almost 1 GHz higher and has faster DDR5 memory, this is an impressive achievement. It also means that Intel has defended their "World's fastest Gaming Processor" claim, but the differences are minimal, when looking at the averages. Individual games will show vastly different results though, the highlights here are Borderlands 3 and Far Cry 5. Borderlands 3, which has been extremely CPU limited in all our testing gains an enormous 43% (!!) in FPS. Far Cry 5 is the most memory-sensitive title in our test suite, +35%, wow! The rest of our games do gain some FPS, but the differences aren't as big. You're probably wondering why Counter-Strike CS:GO is only 5% faster. I suspect it's because the game's hot data already fits into the cache of most processors, so the larger L3 cache doesn't have as much an effect.
Still, even 5% at 1440p is a monumental achievement if you consider that AMD "merely" added more cache and is using the same processor architecture, actually at lower clock speeds. I think it's also important to highlight that we've measured the biggest gains at FPS rates that were already very high in the first place. For example, Borderlands 1080p goes from 97 FPS to 138 FPS. Unless you have a 120 Hz monitor or better, you won't notice the increase in framerate. Latencies might be slightly better though, which could matter to competitive gamers. Due to the way the 3D V-Cache die is stacked on top of the 8-core compute die, all heat has to travel through the 3DV die (and the surrounding structural silicon. When operating at lower voltage, a processor's total heat output will be lower, too. We measured a very reasonable 77°C processor temperature, which is just 2°C above the Ryzen 7 5800X, which runs at higher clocks and voltage, of course. Compared to other Zen 3 Ryzens the heat is concentrated on a smaller area though, because the 5800 uses just a single CCD, whereas the 5900X and 5950X spread the heat over two CCDs. Compared to Intel 12900KS, thermals are a night-and-day difference. While I felt that cooling the Intel chip was a constant challenge, keeping the the Ryzen 5800X3D cool "just works" and no special consideration is needed.
