![]() Intel still clearly has a clock speed advantage and that advantage will keep them priced higher. Its not silly to compare clock speeds as those can be advantages. ![]() The GPU still remains king when it comes to a quality gaming build. But it would be nice to see some tangible improvement regarding fps with CPUs. We know AMD is cheaper and comparing clockspeeds against different architectures between Intel and AMD is silly. We are in the back half of 2019 and we see the same gaming performance that we had in 2015 mainstream CPUs. ![]() It tied basically the same Intel CPUs that have been on the market since 2015 with Skylake. I always use Prime 95 and IBT for stability.įeelinfroggy777 said:It did tie Intel in gaming. Not as sure on AIDA 64 since I never used it. I know Prime 95 heavily uses AVX which is a power hog. AnandTech was able to get it to 4.3GHz all core but with manual OCing it seems to disable boost clocking which in turn cuts 300MHz from single core performance.Īs for the power consumption, the differences are probably what they prioritize. Ryzen has always been pushed to the limit in terms of clock speed and Zen 2 is no different it seems. I'd have assumed any of the Ryzen 3000 would OC to 4.6/4.7Ghz on all cores with decent air/water cooling. Given that the 3950x does a 4.7Ghz single core turbo boost and the 3900x does 4.6Hz single core turbo boost. Velocityg4 said:The overclocking results were disappointing. The AMD Ryzen 2700x hit 104.7W in your old review. The Intel i9-9900K hit 204.6W in your old reviews stress test. I can't see how either is an accurate measure of a CPU under full load. I'd suggest using both in reviews or find another torture test that will fully punish both AMD and Intel for a max load test. While Prime95 gave AMD an unfair advantage. It seems the switch from Prime95 to AIDA 64 gives Intel an unfair advantage in the stress test power consumption test. When you were using Prime95 Intel was punished a lot more. Power consumption: AIDA 64 seems to punish AMD a lot more than Intel. The overclocking results were disappointing. In either case, you can toggle both settings simultaneously for the best of both worlds. AMD says that Auto OC is designed to improve performance in single-threaded workloads, while PBO boosts heavily-threaded applications. Instead, the processor will still respect the limits imposed by the motherboard maker. This new feature grants you some control over the maximum attainable boost clocks by allowing you to add up to an extra 200MHz to the maximum boost clock, but it isn't guaranteed that the processor will reach those speeds at all times, or under all conditions. Motherboard vendors define the power limits for their boards and are developing custom profiles that support a new Auto OC feature. AMD also exposes some of these monitoring features with its Ryzen Master overclocking software. A control loop feeds real-time telemetry data back to the processor, which then dynamically adjusts performance based on thermal and power conditions. ![]() Electrical Design Current (EDC) also indicates the maximum current possible from the VRMs during peak/transient conditions. I suggest you try to set optimally the CO, to increase the CPU’s efficiency.The processor monitors Package Power Tracking (PPT) and Thermal Design Current (TDC) variables, measuring available margin to the motherboard's maximum power output and current, respectively. As you will see in the following graphs, the overall gaming performance is similar, while the applications’ overall performance gets a small boost, lower than 2%. I initially set the curve optimizer at -30 for all cores, and I had instability issues by increasing the frequency to +200, so I had to lower the CO setting to -15, where everything went fine. Precision Boost Overdrive (PBO) allows the processor to run beyond the defined voltage values to the board’s limits and boost at higher voltages for longer durations than the default. For those unaware of what the curve optimizer does, it allows you to set the operating voltage of each core independently. This means that you cannot set specific clocks and multipliers. Because of the pair of different CCX in the 7950X and 7900X, manual overclocking is not available anymore. The only way to overclock the 7000X3D CPUs is through the curve optimizer by enabling the Precision Boost Overdrive (PBO) through the BIOS or Ryzen Master. ![]()
