Intel mini-PCs represented by N95, N100
However, intel is not the only company that makes CPUs for PCs. There are several manufacturers, but... but only two are actually used: Intel and AMD.
The N95 and N100 are ultra-low power, comparable to smartphones
released in the first half of 2023, are built on a 10nm process. (Currently, the most recent process is 4nm. AMD 7840HS, 7890HS, etc. are built on 4nm.) The lower end of the AMD mini-PC market, the 5000U series, released in the first half of 2021, is built on a 7nm process. 5000U series released in the first half of 2021, which are used in AMD mini-PCs, are made on a 7nm process. Power consumption and heat generation for the same work The more advanced the process, the lower the power consumption, The lower the heat and power consumption, the higher the clock speeds that can be achieved. (Even though the intel N-series is ultra-low power, it cannot be said to be ultra-efficient).
MiniPC AMD CPUs are labeled with a number and an alphabet.
For example: 7840HS, 5500U Leading digit: year of release (7 is released in 2023, 5 is released in 2021) Second digit: relative core count or clock speed 2-3: low core count, 4-6: moderate core count, 7-9: high core count (GPU compute unit count varies). The higher the number, the higher the clock speed (GPU clock is also higher). Third digit: 6000 and above is architecture (higher is the latest process), 5000 and below is performance (higher is high performance) Fourth digit: Performance classification for 6000s and above Alphabet: Power consumption HX: 55W or more H: 45W or more (released only up to 6000 units, desktop basic type) HS : 35~54W (for office desktop or notebook) U : 15~28W (for low power mobile)
Everyone will wonder... U ? HS ? H? Difference
The difference in maximum CPU/graphics performance between H or HS and U on a 7000: If all four digits are the same, there is no difference in maximum hardware performance. However, the U model has a relatively tight power limit, so when running CPU multi-core benchmarks, it is 15-30% lower than HS. (There is a difference when running all cores at full load... but single-core benchmarks, or with a few cores playing, are almost identical.) GPU benchmark performance is in the 60-70% range for U, assuming HS is at 100% performance. (Tight power constraints... hard to share with the built-in GPU) The HS line is available from the 7000s... The H line is only available up to the 6000s, so I understand... The 6000/7000s U-line all exist in AMD, but but the U-line of the mini-PC is still only running in the 5000s. (The oddity... the 7735HS is the perfect slightly lower power version of the 6800H...) With the exception of the X nm process number, all other numbers are higher, and higher is better.
Built-in Graphics Gaming Performance
GPU pixel rate, texture rate, and memory clock and channel count. You should also have at least 2 more threads on your CPU than the maximum number of threads used by the game. (If you have less, the CPU will also have a significant impact on the game. Windows itself can eat up 2-4 threads by default. Game manufacturers don't tell you the number of threads. The only way to find out for yourself is to set up two monitors... or just buy a CPU with more cores.) 7840HS/7940HS graphics performance is higher than GTX1650 and similar to GTX 970. 6800H/7735HS graphics performance is on par with the GTX 780. The 5600U's graphics performance is higher than the GTX 650 and lower than the GTX 460 (based on maximum performance, may drop in real-world use due to power limitations).
Power Consumption...
7nm process and... 10nm process... AMD 5600U VS intel N100 as an example. (I think this is the one most people are curious about anyway...) At 18w CPU power limit, the all-core max clock is N100 (10nm) : 3.1Ghz - 4 cores/4 threads 5600U (7nm) : 2.9Ghz - 6 cores/12 threads This may not be obvious. If you measure the power consumption with the N100 locked at 2.9Ghz and correct for the number of cores, you will get the following results intel(10nm) : 2.9Ghz - 6 cores => 25w AMD(7nm) : 2.9Ghz - 6 cores => 18w Power consumption = heat generation The newer the process, whether from the same manufacturer or different, the less electricity and throttling it takes to do the same work. (Note that CPU multicore performance varies significantly due to different thread counts for the same number of cores).
With the N100, you might wonder why you can't run a single LOL on the classic gaming axis.
The 5600U runs very well, but...???? GPU performance is also a big difference, but but the CPU thread count is actually a bigger issue... (I only use 6 threads for LOL... At least 8 threads would be less affected by the CPU... The N100 has only 4 threads, so it loses CPU power in LOL, so it can't even use 100% of the performance of the built-in GPU. Even if you use 100%... It's hard to expect a big performance improvement with the bandwidth of single-channel memory) Hyper-Threading (SMT in AMD), which allows you to spin up threads twice as fast as cores, increases multicore performance by 1.4-1.6x. (So the CPU multicore performance gap between the 5600U and N100 at the same power consumption is about 2x... At peak power, the performance gap is even larger).
Differentiated by usage
I don't play games and don't know much about computers, U-series is enough... (Still, games like LOL run well without stress) If you're just looking to downsize your office desktop, the H-series or 7735HS I need a mini PC to run all my games. 7840HS / 7940HS Â Â AMD 5500U / $220
