► remove from comparison![Intel Celeron N4020](fileadmin/_processed_/4/3/csm_Intel-Pentium-Silver-and-Celeron-chip_136fbc2a2b.jpg)
The Intel Celeron N4020 is a slow dual-core processor (SoC) of the Gemini Lake refresh product family; as such, it is designed for use in laptops and mini-PCs of the most affordable flavor. The Celeron was launched in Q4 2019. Its CPU cores run at 1.1 GHz to 2.8 GHz, the latter being a moderate 200 MHz upgrade over the preceding N4000 chip. Other key specs include a DDR4/LPDDR4 memory controller (up to 2,400 MHz and up to 8 GB, with independent reports claiming as much as 32 GB will work just fine) and an integrated UHD 600 graphics adapter.
Architecture & Features
Just like Apollo Lake family products, the ever-popular N3350 included, the N4020 is manufactured on a really old, as of late 2023, 14 nm process. What makes the newer Celerons different are the slightly improved processor cores with double the L2 cache and also, somewhat counterintuitively, a reduction in physical size.
The Goldmont Plus microarchitecture is not much different from what was used in Gemini Lake processors like the N4000. A relatively large 4 MB L2 cache features prominently on the rather short list of N4020's strong sides, allowing for a marginal increase in performance-per-MHz figures compared to processors of previous generations. Still, Gemini Lake refresh processors are a clear step down from Core i3/i5/i7/i9 series processors, both in performance and in features.
The N4020 has six PCI-Express 2.0 lanes at its disposal. While very few N4020-based SBCs, nettops and laptops feature an NVMe M.2 slot, you can use an NVMe SSD as a boot drive with this processor (read/write rates will be limited to 2 GB/s, though). Furthermore, partial Wi-Fi 5 support is built into the CPU. The Celeron also supports up to eight USB 3.0 ports and two SATA III storage devices.
Please note this is not a user-replaceable CPU. They solder it straight to the motherboard for good (BGA1090 socket interface).
Performance
While slightly faster than the outgoing Celeron N4000, the average N4020 in our extensive database only just manages to match the N6211, as far as multi-thread performance is concerned. These three chips deliver multi-thread CB R15, CB R20 and CB R23 scores that are so low, they lag behind a single-thread score of any half-decent CPU such as an i5-1135G7. In other words, these Celeron N chips are good enough for basic tasks only such as word processing and Web browsing with two or three tabs open at a time.
The Celeron N4120, a quad-core chip with a similar name, has little trouble leaving the N4020 behind in most workloads - which is not to say it is a fast CPU.
Jacking the long-term power limit value up to something like 9 W will help improve system responsiveness noticeably.
Graphics
The UHD Graphics 600 is based on Intel's Generation 9 architecture, much like the HD Graphics 520 or the UHD Graphics 615 or other widespread Intel iGPUs found in Core i3/i5/i7/i9 processors of generations six to ten.
Just like the HD Graphics 500, the UHD Graphics 600 is DX12 compatible. The iGPU's 12 EUs can run at up to 650 MHz. The Iris Plus G7 iGPU that certain 10th Gen Ice Lake processors have packs 64 EUs, for reference. As a low-end solution, UHD Graphics 600 will let you play some seriously old titles, but that's about as far as its talents go.
Perhaps more importantly, this graphics solution can drive up to 3 monitors with resolutions as high as 4096x2160@60. Furthermore, it will have no trouble HW-decoding AVC, HEVC and VP9-encoded videos. The newer AV1 codec will be decoded via software, with the limited CPU horsepower imposing a limit on video resolutions that can be played back without stuttering. 1080p60 videos are out of reach while 720p25 videos run fine, to give you an example.
Power consumption
The low 6 W TDP (also known as the long-term Power Limit) makes it easy for laptop makers to ditch the fan. Performance sustainability will be poor unless the long-term Power Limit is set to a value higher than the default 6 W and a fan is available to aid in heat dissipation.
The Celeron N4020 is built with one of the old 14 nm Intel processes for poor, as of mid 2023, energy efficiency.
AMD Ryzen 7 4980U
► remove from comparison![AMD R7 4980U](fileadmin/_processed_/8/8/csm_ryzen_4000u_chip_adc5cde79d.jpg)
The AMD Ryzen 7 4980U is a Renoir family processor designed for certain Microsoft Surface systems. 4980U has eight Zen 2 cores clocked at 2.0 GHz (base clock speed) to 4.4 GHz (Boost) with thread-doubling SMT tech enabled for a total of 16 threads. The chip is manufactured on the modern 7 nm TSMC process and partly thanks to that AMD promises a 2x improvement in performance-per-Watt over Ryzen 3000 series mobile CPUs.
Architecture
The Zen 2 microarchitecture has brought a sizeable per-thread performance boost compared to the outgoing Zen+ parts. Renoir product family is also the first to introduce 8-core ULV processors to laptop market, keeping power consumption within reasonable limits. This AMD processor family is very impressive from most perspectives. One of the disatvantages to keep in mind is the lack of PCI-Express 4 support, meaning these blazing-fast NVMe SSDs will be limited to 3.9 GB/s tops.
Ryzen 7 4980U is designed to work with quad-channel LPDDR4 memory at up to 4,267 MHz. 8 MB of Level 3 are present in this chip. The Ryzen 7 gets soldered straight to the motherboard (FP6 socket) and is thus not user-replaceable. Please go to our Renoir hub page for more information on the product family.
Performance
The 4980U is the fastest U-class Ryzen 4000 series chip. As such, its clock speeds are 200 MHz higher (both the base one and Boost one) than what the Ryzen 7 4800U has.
It is thus hardly surprising that the average 4980U in our database is in the same league as the Ryzen 7 5800U and also the Core i7-1260P, as far as multi-thread benchmark scores are concerned.
Graphics
In addition to its eight CPU cores, the Ryzen 7 also features the Radeon RX Vega 8 graphics adapter with 8 CUs (= 512 shaders) at up to 1,950 MHz. This iGPU is compatible with FreeSync and DirectX 12 and is able to HW-decode AVC, HEVC, VP9-encoded videos (no AV1 support here). Vega 8 is capable of outputting UHD 2160p60 video signal to several monitors and, similar to Intel's Iris Xe (80 EUs), is good enough for a bit of light gaming on the go, provided one is content with sub-1080p resolutions and low/medium quailty presets.
Power consumption
The APU has a default TDP, also known as the long-term power limit, of 15 W; much like it is with other U-class Ryzen 4000 chips, AMD is fine with laptop makers (Microsoft, in this case) changing that value to anything between 10 W and 25 W.
The 7 nm TSMC process this Ryzen 7 is built with makes for above average, as of mid 2022, energy efficiency.
AMD Ryzen 5 4500U
► remove from comparison![AMD R5 4500U](fileadmin/_processed_/6/6/csm_ryzen_5_4500u_4f257db712.jpg)
The AMD Ryzen 5 4500U is an upper mid-range, hexa-core processor of the Renoir product family. The APU was unveiled in H1 2020; it is designed for use in thinner, lighter laptops. Its six Zen 2 CPU cores run at 2.3 GHz (base clock speed) to 4.0 GHz (highest Boost frequency possible). Ryzen 5 4500U features the Vega 6 iGPU.
The sole advantage of Ryzen 5 4600U over Ryzen 5 4500U is the thread-doubling SMT technology support. The former has SMT while the latter does not.
Architecture
Zen 2 is a resounding success, delivering massive improvements over outgoing Zen Plus-based processors. Ryzen 5 4500U is manufactured on the cutting-edge 7 nm TSMC process; it is compatible with dual-channel DDR4-3200 or quad-channel LPDDR4-4266 memory. This processor has 8 MB of Level 3 cache.
While the APU uses Zen 2 cores just like the desktop-grade Ryzen 3000-series processors do, Ryzen 7 3800XT included, it does does not have PCI-Express 4.0 support. It does feature several PCI-Express 3.0 lanes for connecting discrete graphics cards, SSDs and other devices. Four PCI-Express 3.0 lanes allow for read/write rates of up to 3.9 GB/s provided a suitably fast NVMe SSD is used.
Ryzen 5 4500U gets soldered permanently on to the motherboard (FP6 socket interface) and is anything but user-replaceable.
Performance
The average Ryzen 5 4500U in our database nearly matches the Core i5-11300H, the Core i5-11320H and also the AMD Ryzen 3 5300U as far as multi-thread benchmark scores are concerned - thus delivering an undeniably impressive performance jump over the outgoing Ryzen 5 3500U.
Thanks to its decent cooling solution and a long-term power limit of 38 W, the Xiaomi RedmiBook 16 R5 is among the fastest systems powered by the R5 4500U that we know of. It can be about 20% faster in CPU-bound workloads than the slowest system built around the same chip in our database, as of August 2023.
Graphics
Just like its name suggests, the Radeon RX Vega 6 graphics adapter has 6 Compute Units (6 x 64 = 384 unified shaders). In the case of Ryzen 5 4500U, this graphics adapter runs at up to 1,500 MHz. The iGPU definitely supports UHD 2160p monitors at 60 Hz; it will have no trouble HW-decoding HEVC, AVC, VP9, MPEG-2 and other widespread video codecs. AV1 is not supported though; such a video will have to be software-decoded for much lower energy efficiency.
Vega 6 will let you play many titles of 2020 and 2021 as long as you stick to low settings and low resolutions. F1 2021 (720p, Low) runs at 32 fps; Outriders (720p, Low) runs at 27 fps, to give you an example or two. As the iGPU has no VRAM of its own, it is paramount that fast system RAM is used.
Power consumption
This Ryzen chip is very energy efficient, as of mid 2022, thanks to the cutting-edge 7 nm TSMC manufacturing process and the mature Zen 2 architecture.
The Ryzen 5 4500U has a default TDP (also known as the long-term Power Limit) of 15 W that can be changed to anything between 10 W and 25 W by laptop makers if required, a right they use more often than not. Clock speeds and performance will change accordingly as a result. By going for the lowest value, it will be possible to use the APU as the heart of a passively cooled tablet, laptop, mini-PC.
