Among other useful things, this is going to identify exactly what motherboard you have installed. So I use CPU-Z for basic diagnostic information. That will also let you compare L1/2/3 cache sizes, configurations, CPU and bus clock rates and multipliers, etc.Īs for the cost of electricity, you really need to measure it at the wall with a kill-a-watt or similar to eliminate variables like PSU efficiency if you want to be sure how much it's going to cost you. You can probably see and adjust ("overclock") the RAM settings in your BIOS setup, or you can use a tool like CPU-Z to see it from Windows. But there are more variables than that, perhaps the 4790k machine does not have the fastest RAM that it can use or has the slots installed wrong so that it can't use dual-channel, or perhaps it has PC3-12800 with 11-11-11 timings (13.75 ns latency) while the 2600k machine has PC3-10600 with 7-7-7 timings (10.5 ns). Those are both fairly recent CPUs, so I expect both use DDR3 with different clock rates, like 1333 vs.
That means that your memory latency and bandwidth are likely the critical bottleneck, and the CPU is spending most of its time waiting for memory channels. I don't know the details, but the PoW function for CN is designed to be ASIC- and GPU-resistant by making it extremely memory-intensive. But you could upgrade it for about $100 to complete it, with the above.Īlso check YouTube by laptop model or specs, and the games you wish to play, to confirm it'll run to your expectations.Īnd, check reviews regarding the model's screen/display, battery life, and whether it has overheating issues. > Plus there is an open spot for a standard 2.5"drive. Since there is only a 256gb SSD, the Q&A section of newegg thankfully states that you can also add another SSD or HDD: Try to find another stick of the same model and specifications. Once opened, under the SPD tab, you can find the brand and model number. You can find the current memory type, brand, model, and slot capacity by downloading CPU-Z. If you want to upgrade memory (RAM), then you will need the same type, timings, voltage and chip type. Upgrading it with another stick would improve gaming performance quite a bit. I don't follow the laptop space much, but, I think the best alternative at that price is otherwise the mx150, which is much worse.
