日本AMD Ryzen 7 4800U vs Intel Core i7-10710U – Comet Lake is down but not entirely
We still have unfinished business with the upcoming Zen 2 CPUs – there is no comparison with Comet Lake from our side. The 4800U has a 15W TDP and we saw that the 10th gen Ice Lake CPU like i7-1065G7 doesn’t stand a chance when its compared to a ULV Zen 2 processor.
If we look at the current Intel mobile lineup we can spot that there is another one worthy competitor for 4800U – i7-10710U. That’s right, until now, we compared the Zen 2 CPUs with Coffee Lake and Ice Lake CPUs but somehow Comet Lake was out of our sight. The i7-10710U has more cores and threads than its Ice Lake sibling (i7-1065G7) and maybe it’ll be close to 4800U? Maybe, let’s check it.
Of course, as soon as we get our hands on the new Ryzen CPUs, we’ll update this article with results from our own lab.
Quick Specs
The AMD Ryzen 7 4800U has 8 cores and 16 threads “fitted” in just a 15W TDP. That’s the magic of the 7nm tech process – a lot of cores and logical threads combined with really low TDP values thanks to the more advanced and efficient architecture. Additionally, AMD is able to fit the powerful and new RX Vega 8 with faster 8 CUs (around 60% more than the ones of the Zen+ iGPUs) which is two times faster than Intel Iris Plus G4. This CPU has 8MB of cache and impressive supported memory frequencies – DDR4-3200MHz; LPDDR4-4266MHz.
The i7-10710U is a 10th gen 14nm Comet Lake CPU with 6 cores and 12 threads. Intel has an advantage with its bigger cache size – 12MB. The base clock of the Comet Lake CPU is lower than then 4800U one – 1.10 GHz. This isn’t bad – when the CPU load is light the Comet Lake representative will not boost a lot and this is good for power consumption and battery life. The boost clock of i7-10710U is really high considering its low TDP – 4.70 GHz. The Comet Lake processor shows its age when it comes to supported memory frequencies – DDR4-2666, LPDDR3-2133. The iGPU is the refreshed Intel UHD Graphics.
More detailed specs here – AMD Ryzen 7 4800U / Intel Core i7-10710U
Specs table:
| AMD Ryzen 7 4800U | Intel Core i7-10710U | |
|---|---|---|
| Cores / Threads | 8 / 16 | 6 / 12 |
| Base / Max frequency | 1.80 – 4.20 GHz | 1.10 – 4.70 GHz |
| Cache | 8 MB L3 Cache | 12 MB L3 Cache |
| TDP / up / down | 15W / 25W / 10W | 15W / 25W / 12.5W |
| Memory support | DDR4-3200MHz; LPDDR4-4266MHz | DDR4-2666, LPDDR3-2133 |
CPU Benchmarks
The difference is 21% – it’s a lot but keep in mind that the i7-10710U has 2 core and 4 threads less than 4800U.
Results are from the Cinebench 20 CPU test (the higher the score, the better)
GPU Benchmarks
As we already mentioned, the Comet Lake processor uses refreshed UHD graphics but look at the results in the table down below. Maybe Intel will need around 10 more refreshes of this iGPU to equal the performance of the new Vega 8 with 8 CUs.
| AMD RX Vega 8 | Intel UHD Graphics | |
|---|---|---|
| 3DMark Firestrike | 6110 (+446%) | 1119 |
Check this out too – the upcoming AMD iGPU is around 30% slower than NVIDIA GeForce GTX 1650 Max-Q which is a fast dedicated graphics with 1024 stream processors and 4GB GDDR5 memory. That new AMD RX Vega 8 looks like a real beast of an iGPU.
Results are from the 3DMark: Time Spy (Graphics) benchmark (higher the score, the better)
Results are from the 3DMark: Fire Strike (Graphics) benchmark (higher the score, the better)
Results are from the 3DMark: Wild Life benchmark (higher the score, the better)
Results are from the Unigine Superposition benchmark (higher the score, the better)
Verdict
For the first time since (we’ve made some previous comparisons based on leaked Zen 2 results), 4800U doesn’t look so powerful. Or at least when it comes to processing performance. There is no doubt, the Ryzen CPU has a 21% higher score but it has 2 cores and 4 thread more than 10710U. Our opinion is that the 10th gen Comet Lake CPU is still a decent performer that has good computing performance. Don’t forget the fact that its direct competitor will be the Ryzen 5 4600U which has the same amount of cores and threads. It sounds like an interesting comparison but we have to wait a bit more for it.
On the other hand, the iGPU of the 4800U is fantastic. AMD has put a lot of fresh power in those new CUs – they are really fast and strong. When the new Vega 8 is compared with Intel UHD graphics the latter looks pity because the “red” integrated video card wipes the floor with Intel’s iGPU. This is a really astonishing performance – a 30% lower score than GTX 1650 Max-Q which is a really promising result. With 4800U the future buyers will get a really fast and efficient 7nm CPU alongside superfast iGPU and maybe most of them will not need a dedicated graphics solution.
Still, the 4800U beats the Core i7-10710U because of its higher core count. The i7-10710U stands its ground because its real “enemy” is Ryzen 5 4600U. When the time comes we all are going to see the real difference between a 6-core Zen CPU and a 6-Core Comet Lake processor like i7-10710U. Even then, we can assure you that 4600U has a much faster iGPU then Comet Lake CPUs – RX Vega 7 has 7 CUs and that’s why 4600U will be a better choice as a whole package – CPU and iGPU performance.
Of course, as soon as we get our hands on the new Ryzen CPUs, we’ll update this article with results from our own lab.
