Who should i5/i7 choose? Is there a big difference? i5-13490F, i7-13790F depth test

1. Is the performance of i5 and i7 still similar?

Since the release of the Zen architecture in 2017, Intel and AMD have entered into a fierce involution in the competition for CPU performance. As the product competition between the two parties intensifies, the performance gap between different grades of CPU products of the same generation has been significantly widened.

So, is the past view that "i5 and i7 have similar performance, and the cost performance of i5 is relatively high" still holds true?

Bring the Intel i5-13490F & i7-13790F test report today.

Product appearance introduction:

From the front of the CPU, the appearance of the two is basically the same. The more obvious difference is the model number on the top cover of the CPU and the contacts on the PCB for distinguishing the model number.

On the back of the CPU, you can see that there is a relatively large difference in the capacitor layout, so the i5-13490F and i7-13790F should be manufactured with wafers of different specifications.

The capacitor on the back of the CPU is still relatively fragile, so be careful not to bump it when installing it.

CPU specification introduction:

Let’s take a look at the specifications of the CPU. The core size of the i5-13490F is 6P+4E, and the core size of the i7-13790F is 8P+8E. In terms of cache size, the i5-13490F triple cache is 24MB, and the i7-13790F triple cache is 33MB. The maximum turbo frequency is 4.8G for i5-13490F and 5.1G for i7-13790F.

五、磁盘性能、平台功耗测试

磁盘测试部分用的是CrystalDiskMark6,1G的数据文件跑9次,这样基本可以排除测试误差。测试的SSD分别是 535 480G 和7000速度的群联E18方案 SSD 1TB,都是挂从盘。PCI-E 5.0暂时没有合适的SSD可供测试所以磁盘测试也会扩展为SATA(芯片组引出)、MVNe 4.0(芯片组引出)、MVNe 3.0(芯片组引出)、MVNe(CPU引出)这4种状态。

Who should i5/i7 choose?  Is there a big difference?  i5-13490F, i7-13790F depth test

从测试结果来看i7-13790F的表现较好,与i9-13900K的成绩大致相当,但是i5-13490F的表现会差一些,主要是芯片组引出的通道性能表现偏低。

六、数据汇总与结论

·   CPU的综合性能,i5-13490F 与 i7-13790F的性能表现相当好,i7-13790F性能与锐龙9 7900X比较接近,可以比i9-12900K领先约7%。i5-13490F性能略低于i5-12600K,落后约4%。i5-13490F与i7-13790F之间的性能差距约44%,区别非常明显。

·   搭配独显3D性能,13代整体表现也会略好于12代规格接近的产品。i5-13490F与i7-13790F之间的性能差距约5.6%,相比12代差距有所拉大。所以如果使用性能为旗舰或次旗舰的显卡,CPU会产生较为明显的区别。

·   综合功耗(整机),13代酷睿的功耗提升较为明显,13代F系列的CPU的综合功耗已经超过了12代的K系列CPU。所以i5-13490F虽然极限功耗不是特别大但是对散热也有了一定要求,i7-13790F则应该使用旗舰风冷或360水冷才能完全发挥性能。

最后上一张CPU天梯图供大家参考。性能部分仅对比与CPU有关的测试项目,并不包含游戏性能测试的结果。由于2017年开始,系统、驱动、BIOS对CPU性能的影响非常巨大,所以这张表仅供指向性的参考。天梯图中由于显卡变更,所以功耗部分会出现暂缺的情况。

由于我的测试方式主要针对日常使用环境,单线程权重比较高对HEDT CPU并不友好。

Who should i5/i7 choose?  Is there a big difference?  i5-13490F, i7-13790F depth test

总结:

关于CPU性能:

The performance difference between i5-13490F and i7-13790F is still very obvious. The i5-13490F is economical and applicable, and its performance limit is not high, but it can handle most real-time operation scenarios. The i7-13790F has performance close to that of the sub-flagship, and the multi-thread full load effect is much stronger, and it has a greater advantage in productivity scenarios.

About collocation independent display:

The difference between i5-13490F and i7-13790F is strongly linked to the performance of the GPU itself, when only games are considered.

If it is a flagship or sub-flagship graphics card, the difference between the two will be more obvious. It is necessary to consider the i7-13790F to fully exert its performance.

60~70 mid-to-high-end graphics card i5 and i7 are both available, and you can consider it according to your own needs for CPU performance. For weaker graphics cards, it is recommended to directly i5-13490F to maintain the balance of the overall machine configuration.

About power consumption:

Compared with the 12th generation, the power consumption of the same level products of the 13th generation is still more obvious.

The i5-13490F is controlled below 125W , so it can still be adapted to most chassis, as long as the radiator is a single tower with decent performance, it is enough.

The i7-13790F directly reaches the level of 270W , so the radiator is basically bound to 360 water cooling, and the cooling capacity of the chassis also needs to be reserved for redundancy.

Generally speaking, the performance improvement of the two CPUs, i5-13490F and i7-13790F, is quite obvious.

In addition to relying on increasing the core and increasing the frequency, the 13th generation also has a more obvious performance improvement in the architecture, and even the i7-13790F exceeds the i9-12900K of the previous generation flagship.

It can be seen that the current CPU performance is in a state of considerable involution, and the more mainstream CPU products can be greatly improved. This is naturally the gospel for users who want to buy CPUs now.

However, the power consumption of Intel CPU is quite "in-depth". Although the energy consumption ratio is not so sensitive on the desktop level, the excessively high full-load power consumption of the i7-13790F will still affect the choice of the installed solution. This is something to keep in mind when choosing a configuration.
