Lenovo Legion 5 With Amd Ryzen 5 4600h & Gtx 1650 Laptop Performance Review
Load power consumption alone doesn’t tell us anything about efficiency, though. Some chips finish work quickly despite their high load power draws, while others take much more time to complete a job despite deceptively low peak figures at load. After our trial run with DAWBench in our last CPU review, we read the instructions for the benchmark and discovered that we had been doing it wrong . We’re able to run both the DAWBench DSP benchmark, which tests the number of instances of a VST plugin a CPU can handle before being overloaded, and the DAWBench VI test, which tests virtual instrument and sampler performance.
The memory controller on Nehalem-era chips had stupid compatibility issues and weren’t exactly friendly with memory overclocking . Memory controller on Sandy Bridge and onward fixed most of silly “headaches”. Intel didn’t get a handle on integrated memory gtx 1090 controller in terms of latency and actual bandwidth throughput until Sandy Bridge though. However — and this is borne out in game benchmarks — other workloads are much more sensitive to cache latency when there’s a miss that requires jumping between CCXs.
Both Intel CPUs come with 6 cores and 12 threads making them a far attractive value. It took the Ryzen 5 laptop just 17 minutes and 48 seconds to shrink a 4K video to 1080p using the HandBrake application. The Core i5 model took 20 minutes and 4 seconds to perform the same task. The main focus of this redesign was to boost IPC performance in order to attain single-core performance that could finally topple Intel. While a good portion of this was through incredibly complicated work reducing prediction latency and implementing faster code fetching, a huge part of it is the way AMD redesigned the die itself.
All of the Ryzen CPUs handily beat out their comparable Intel competition here, though. The Cinebench benchmark is powered by Maxon’s Cinema 4D rendering engine. The test runs with a single thread and then with as many threads as possible. Raw memory bandwidth is important, but so is the latency gigabyte gtx 1060 3gb of those accesses. All else being equal, the Ryzen chips lag every Intel CPU in this test by a wide margin. Those higher latencies, combined with the bandwidth pressure exerted by many hungry cores, could have an adverse effect on Ryzen CPUs’ performance in memory-intensive operations.
In contrast, all of the Intel i7 processors are based on Intel’s Kaby Lake microarchitecture, which is a type of microarchitecture that uses a 14 nm manufacturing process. This microarchitecture was developed in order to achieve faster CPU clock speeds than ever before, better graphics, and higher Turbo boost frequencies. Both AMD Ryzen and Intel 8th Gen Core processors have four cores, which give you eight simultaneous threads.
If you aren’t a fan of overclocking, you could opt for the Ryzen X, which has a more aggressive automated overclocking profile and a higher TDP to support higher sustained boost clock speeds out of the box. But even at its newly discounted price, it’s almost $50 more for only a few hundred megahertz more. 32 MBGPU—TDP180W180W180WPrice$300$620$700What do you get with the 3000 series Threadripper processors?
Most important of all, Zen 2 also brings with it a hefty increase to instructions per clock – some 15% in fact. That’s only a little shy of enough extra compute brain power to close the gap between AMD and its age-old rival, Intel, in gaming workloads, and rendering the performance delta between the two companies’ finest ostensibly negligible. As you will have seen from our review above, both kinds of processors are fantastic considerations. The one that you should choose depends greatly on what it is you need the processor for. On the other hand, if you’re looking for a processor that can handle larger workloads and gaming with speed and efficiency, look to an Intel i7 processor. Plus, in conjunction with Kaby Lake microarchitecture, the Intel i7 processors are also powered by Intel’s Optane technology, which works to improve storage speeds and improve overall efficiency.
