As all the processors compared above belong to the same brand modifier, i5, the later the generation, the better is its overall performance. Hence, the 11th gen CPUs are better than the 10th generation, which are in turn better than the 9th generation.
Number of processors
Among the laptops, Intel is gradually phasing out the 9th generation CPUs. H and HF are the only series of processors available in the 9th gen laptop CPUs. However, a range of 10th and 11th gen processors are available. Among desktops CPUs, all the generations offer ten models each.
Intel follows a simple procedure of letter suffixing to indicate the level of performance of the specific processor chip.
The letter suffixing in the laptop CPUs is as under.
The 9th generation i5 laptop processors are available in the H and HF series. H denotes High performance, and HF signifies high performance without offering integrated graphics.
The 10th generation i5 laptop CPUs are available in U, Y, H, G1, G4, G7, NG7. U denotes ‘Low Power,’ whereas Y signifies ‘Ultra Low Power.’ These processors have low TDP values and consume less power.
In contrast, the H series processors are high-performance CPUs. The G letter suffix CPUs indicates the performance levels that the CPU can extract from the integrated graphics, with 1 being the lowest and 7 the highest performing.
The 11th generation i5 laptop processors come in the H and G7 series alone. Hence, they are characterized by high-performance levels.
The letter suffixing in the desktop CPUs is similar to that of the laptops.
Generally, you find T, K, F, KF, and the No Suffix series in desktop processors. The 11th generation offers the B series, the best performing of all desktop processors. T represents a power-optimized lifestyle, whereas K signifies unlocked processors, thereby offering accessible overclocking.
The F and KF series do not come with integrated graphics, with the KF series offering to overclock. The B series signifies Ball Grid Array, similar to what is available in notebooks. Finally, the No Suffix series is a characteristic of the desktop processors alone.
All the 11th generation laptop processors and the Ci5 11500B Desktop CPU come with 10nm fabrication technology.
All CPUs in the 9th and 10th generation except (Ice Lake G1, G4, G7, and NG7 Series) feature 14nm semiconductors.
The 10th Gen Ice Lake Mobile CPUs with G1, G4, G7, NG7 series are 10 nm.
The lower the nanometer number, the better is the performance, and the higher is the processor’s efficiency.
As the transistor size decreases, it is possible to fit more in the same unit area. Therefore, it is capable of better performance.
Secondly, smaller transistors consume less power and generate less heat. Thus, they are more efficient.
The 9th generation laptop CPUs are quad-core processors, whereas the H-series processors in the 10th and 11th gen i5 are hexa-core. The rest of the CPUs in both these generations are quad-core. All laptop processors in the 9th to the 11th gen support hyperthreading.
All the CPUs in the 9th to 11th gen are hexa-core processors in the desktop category, with the 10th and 11th gen CPUs supporting hyperthreading. However, the 9th generation desktop i5 CPUs do not support hyperthreading.
Clock Frequency Range
The 10th generation laptop CPUs display a higher clock speed range because the U and Y series processors have lower base speeds. As a result, they are better at performing low-intensity tasks as they consume less power in the process. The H series CPUs, being high-performance models, come with higher clock speeds.
In the desktop processors, the 11th gen CPUs display the best clock frequency range.
All the desktop CPUs in the 9th to 11th generation support up to 128GB DDR4 memory, with the 11th generation being distinctly better as they support higher speeds up to 3200 MHz.
In the laptop CPUs, the 11th generation processors are better equipped because they support LPDDR4x memory that consumes less power than DDR4. Besides, some 11th gen i5 CPUs support up to 4267 MHz speed.
Moreover, the LPDDR4x RAM available in the 11th gen laptop CPUs provides nearly 50% more bandwidth than the earlier generations.
Hence, it is helpful for gamers and content creators because the better RAM allows more multitasking.
The 11th generation quad-core i5 laptop processors come with Intel Iris Xe graphics, whereas the hexa-core CPUs support Intel UHD graphics.
The G and NG series in the 10th gen support Intel Iris Plus graphics. The F and KF CPUs do not support integrated graphics, whereas all the other 9th and 10th gen i5 laptops come with Intel UHD graphics.
All the processors in the 9th to the 11th generation i5 CPUs support integrated graphics in the desktop category, except for those in the F and KF series. The 11th gen Intel UHD 750 graphics is a better version than the Intel UHD 630 graphics.
The 11th generation i5 processors come equipped with advanced technologies than the earlier gen processors. For example, they support DirectX 12.1 and PCIe 4.0 compared to DirectX12 and PCIe 3.0 supported by the 9th and 10th gen CPUs.
Thunderbolt 4 connectivity is available in all 11th gen i5 processors and the 11500B CPU in desktops. The other CPUs do not support Thunderbolt 4.
Thunderbolt 4 is an advanced version of Thunderbolt 3 as it supports multiple display outputs (1 x 8K resolution or 2 x 4K resolution). Where data transfer speeds are concerned, Thunderbolt 3 and 4 offers speeds up to 40Gbps.
Thunderbolt 4 also enables the charging of laptop batteries. Thunderbolt 3 is available in the 10th gen laptop CPUs but not in the 9th gen processors.
Intel Optane Memory, a dual/hybrid storage resource, is available in all CPUs from 9th to the 11th gen i5. This storage comprises HDD and SSD storage to supplement the system storage offerings. Besides, it helps in enhancing processor speeds.
Intel DL Boost is available in the 10th and 11th gen laptop processors and the 11th gen desktop CPUs. Similarly, the 10th and 11th gen i5 laptop CPUs support Intel Adaptix technology.
The 10th and 11th generation CPUs offer Wi-Fi 6 (802.11ax) and Bluetooth v5.0 connectivity to deliver faster wireless speeds.
Which processor should I choose?
A casual user who does not use the laptop for activities other than internet browsing, watching multimedia, or normal computing activities can conveniently go for the 10th gen CPUs because the U and Y series processors consume less power and are economical to use.
On the other hand, if you desire a higher level of performance, the 9th gen H and HF series should also suffice. However, you will need a discrete graphics processor if you go for the HF CPU as it does not offer integrated graphics.
The 11th gen Ci5 CPU is a better performer as the H, and G7 series deliver high-level performances. In addition, installing a discrete graphics card can supplement the Intel Iris Xe graphics and enable excellent gaming and other graphics-intensive activities.
