AMD’s line of processors Ryzen has been the hot new thing in the CPU world for the last few years. Since their release, the Ryzen line has been highly regarded and it has been praised for its performance. In this comparison, we have the recently released Ryzen 5 4500U versus last year’s Ryzen 5 3550H.
It is important to note that the new one is an energy-efficient model with 15W TDP while the consumption of the older is 35W. In other words, 4500U could be integrated into slimmer and more portable notebooks.
There are two key differences between the AMD Ryzen 5 4500U and the Ryzen 5 3550H. The first one is that the newer Ryzen 5 4500U has double the cache – 8MBs, compared to the older one which has just 4MBs. This increase should in turn lead to better performance in many applications. The second key difference, as we mentioned above, is that the 3550H requires a much more powerful cooling system as its TDP is rated at 35W.
|AMD Ryzen 5 4500U||AMD Ryzen 5 3550H|
|Cores / Threads||6 / 6||4 / 8|
|Base / Max frequency||2.30 – 4.00 GHz||2.10 – 3.70 GHz|
|Cache||8 MB Cache||4 MB Cache|
|TDP / up / down||15W / 25W / 10W||35W / 40W / 12W|
|Memory support||DDR4-3200MHz, LPDDR4-4266MHz||
|Integrated graphics||Radeon RX Vega 6 (Ryzen 4000)||Radeon RX Vega 8 (Ryzen 2000)|
In terms of CPU power, we can see that the Ryzen 5 4550U does a lot better than its older sibling. In our 3D rendering benchmark, the 4550U takes the lead with a whopping 42% difference, and in our Photoshop benchmark 3550H is more than 50% slower.
Results are from the Cinebench 15 CPU test (the higher the score, the better)
Results are from the Fritz chess benchmark (the higher the score, the better)
In the graphics department, the lead is taken by the Ryzen 5 4550U again. On average, the 4550U does 8-24% better in graphics-intensive tasks (17% better on average).
Results are from the 3DMark: Fire Strike (Graphics) benchmark (higher the score, the better)
Results are from the Unigine Heaven 3.0 benchmark (higher the score, the better)
Results are from the Unigine Heaven 4.0 benchmark (higher the score, the better)

|AMD Radeon RX Vega 8 (Ryzen 2000/3000)||106 fps||68 fps||36 fps|
Overall, in this comparison, the Ryzen 5 4500U is the clear winner. In our CPU benchmarks, the 4500U did about 50% better than the 3550H, and in the graphics-intensive tasks, the RX Vega 6 (Ryzen 4000) has 17% better performance on average, compared to RX Vega 8 (Ryzen 2000/3000). In real gaming tests, the advantage of RX Vega 6 in Ryzen 4500U is 9.3%.
These tests clearly show the gap between the two generations as the Ryzen 4000 is not only much more energy-efficient but it’s much more powerful as well.
