AMD launched the Ryzen 8000G series APU at the beginning of this year, in fact, at that time, I guessed that they would definitely come out with a corresponding non-core graphics version, this kind of thing Intel and AMD have done, the more recent is Ryzen 5 7500F and Ryzen 7 5700, Ryzen 5 5500 These products, and this time Ryzen 8000 has two coreless graphics versions, namely Ryzen 7 8700F and Ryzen 5 8400F, they are only for the channel OEM market, not for the retail market, so there will be no suggested retail price.
Among them, the Ryzen 5 8400F is directly aimed at the cost-effective market, especially the whole machine platform with a budget of less than 3999 yuan with a dedicated display, in the past, AMD basically only had the AM4 platform to choose from in this market, and now players can choose the newer Zen 4 architecture processor and use DDR5 memory.
Ryzen 8000F Processor Introduction
Ryzen 7 8700F is the product of Ryzen 7 8700G after removing the core graphics, still 8 cores and 16 threads, with 8MB L2 cache and 16MB L3 cache, the core frequency is reduced from 4.2~5.1GHz to 4.1~5.0GHz, although the core graphics are removed, the NPU is still reserved, and Ryzen AI is supported.
Ryzen 5 8400F feels like it is a product of Ryzen 5 8500G without the core display, but in fact it is changed from Ryzen 5 8600G, and its core size can be found from the official website 178mm2, which means that it uses a big Phoenix, it has 6 Zen 4 cores, has 6MB L2 cache and 16MB L3 cache, base frequency 4.2GHz, boost frequency 4.7GHz, 4.3 ~ than Ryzen 5 8600G5.0GHz is a bit of a difference, and it also removes the NPU.
The TDP of the two new processors is still maintained at 65W, because it uses the Phoenix core, it is different from the Ryzen 7000 processor, the L3 cache is only half, it does not support PCIe 5.0, and the graphics card only has x8 bandwidth, but the processor has changed from MCM structure to a single chip, and the process has also been upgraded from TSMC 5nm+6nm to 4nm, The overall power consumption is better controlled, and the Phoenix also has a built-in USB4 controller, which can provide USB4 interface, but this needs to be supported by the motherboard.
Wuji Ryzen 5 8400F machine introduction
Since the two Ryzen 8000F processors are sold in the form of a complete machine, the sample we received is naturally a complete machine, which is provided by Wuji, the brand was founded in 2012, with two sub-brands of IPASON and Wuji VTG, headquartered in Wuhan City, Hubei Province, is a high-tech enterprise integrating R&D, production, sales and service. Pansheng Technology is mainly engaged in high-performance customized computers, notebook computers, all-in-one computers and related peripheral digital technology products, and provides overall industry solutions based on PC commercial needs.
This machine uses a Ryzen 5 8400F processor and a Radeon RX 6750 GRE 10GB graphics card, and the price is only 3898 yuan, which is really cost-effective, let's take a look at what parts are used in this machine.
This machine uses AMD Ryzen 5 8400F processor, with Samsung DDR5-5600 16GB memory, the motherboard is Mingxuan Challenger B650M WiFi6, Hankai RX 6750 GRE 10GB graphics card, Kingston PCIe 4.0 512GB SSD, Patriot Dark Knight 650DK 500W power supply, climb custom quad heat pipe glare fan heatsink, accumulated to the obsessive L5 chassis, equipped with three 12cm RGB fan, the shape of the sea view room is still very good-looking.
Hankai RX 6750 GRE 10GB alloy PRO graphics card only needs a single 8pin power supply, and the dual-fan design also makes the graphics card relatively short, but the price is that the TGP of the graphics card is only 158W, which is slightly lower than the 170W of the public version.
The model of Kingston's SSD is OM8SEP4512N-A0, and it is a product for OEMs, with a sequential read speed of 3100MB/s for 512GB capacity, and a maximum sequential write speed of 1300MB/s, it should be noted that it uses QLC flash memory.
The matching radiator is a standard four-heat pipe tower air cooler, equipped with a 12cm glare fan, and it is no problem to use air cooling to suppress only 65W Ryzen 5 8400F. The price of this configuration is only 3898 yuan, which is really cost-effective,Of course, there are problems,Single memoryThis is obviously to reduce the cost,Single-channel memory has a great impact on the performance of the CPU,It is recommended to add memory after you get it。 In addition, the SSD is only 512GB, which is obviously not enough for the whole game machine, and the Mingxuan Challenger B650M used only has one M.2 port, which leads to the expansion only through the SATA port. The two fans on the side panel of the case are exhausting air outward, which is completely useless for heat dissipation.
Test platform with instructions
This whole machine is also AMD's current main promotion of the configuration below 3999 yuan, and its competitors are close in price, using Core i5-12400F/12490F processor with RTX 4060 graphics card, because we have built a comparison platform with similar configurations according to similar to this kind of machine, the processor is Core i5-12400, using MSI B760M EDGE TI WIFI motherboard, ASUS DUAL RTX 4060 O8G graphics card.
In order to give full play to the full performance of the CPU, both platforms use the Colorful Tomahawk DDR5-6000 16GB*2 set, and the timing is 30-36-36-76.
Benchmark performance testing
Although Ryzen 5 8400F and Core i5-12400 are both 6 cores and 12 threads, the all-core frequency gap between the two of them is still quite large, Ryzen 5 8400F all-core can run above 4.6GHz, but Core i5-12400 is only 4.0GHz, so the gap in computing power between the two is not small, and the processor computing project Ryzen 5 8400F has about 15% higher than the Core i5-12400 in terms of integer and floating-point computing power. In the processor multimedia project, the Ryzen 5 8400F runs the AVX-512, so the performance lead is very large.
Creative Ability Test
In fact, it can be seen from the frequency that the Ryzen 5 8400F will have a great advantage over the Core i5-12400, after all, the latter's maximum turbo frequency is only 4.3GHz, while the maximum boost frequency of the Ryzen 5 8400F can reach 4.7GH. From the test results, it can be calculated that the single-threaded performance of the Ryzen 5 8400F is 10% higher than that of the Core i5-12400, and the multi-threaded performance is as much as 22% higher.
Gaming testing
Since this is a comparison of platforms, the two CPUs are paired with different graphics cards, Ryzen 5 8400F uses RX 6750 GRE 10GB, while Core i5-12400 uses RTX 4060, and the tests are all conducted at 1080p resolution, and all games are turned on with the highest image quality.
From the perspective of game testing, the game performance of the Ryzen 5 8400F with RX 6750 GRE 10GB platform is roughly similar to that of the Core i5-12400 with RTX 4060, and three of the seven games tested are Ryzen 5 8400F platform higher than the Core i5-12400 platform, and two are tied, while the Ryzen 5 8400F is paired with RX 6750 GRE The price of the 10GB machine is mostly within 4000 yuan, and most of the latter are above 4000 yuan, and they may give you DDR4 memory, and the former is more cost-effective as a game platform.
Temperature and power consumption testing
In terms of power consumption test, this time we have upgraded the device, now we can detect the power supply power of the motherboard's CPU and the 24pin power supply interface at the same time, and also check how much power the graphics card takes from the PCI-E slot, so that the software can automatically calculate how much power the CPU takes from the power supply 12V, it should be noted that although the graphics card has been deducted, other things on the motherboard that use 12V power supply will still affect the monitoring results, such as water pumps and fans, so we will still use the CPU recorded by the software Package power consumption data.
In addition, it must be noted that at present, we are measuring the input power of the CPU on the motherboard, not the direct CPU power supply, so theoretically it should be slightly higher than the actual power supply power of the CPU, and it will change more because of the different motherboards, but this test data still has a high reference value, because the power supply is actually the power supply to the motherboard rather than directly the CPU, so for the selection of power supply, it is more practical to directly test the power supply power of the CPU power supply interface.
The ambient temperature at the time of the test was 27°C.
In terms of power consumption, Ryzen 5 8400F is the same as the Ryzen 7 8700G and Ryzen 5 8600G we tested before, the CPU package power consumption must not exceed 88W, and the all-core frequency of Ryzen 5 8400F is around 4.65GHz when baked, and the power consumption is higher than that of the Core i5-12400, but the frequency is much higher. However, the performance in terms of temperature is not very good, mainly because the internal thermal conductivity material of the Ryzen 8000 series CPU is made of silicone grease, which is much weaker than brazing, which leads to a very high full-load temperature of the CPU.
The standby is not a complete desktop standby, but is monitored with HWinfo on, and when testing the Ryzen 5 8400F, we found that the CPU input power recorded by the instrument is lower than the CPU package power reported by the software, and then we looked at the 24pin power supply data intercepted by the instrument, and found that the +5V current is a bit high when standby, it should be that the Ryzen processor has a built-in USB controller, so it should be directly from the +5V power, and this part of the power instrument will not be included in the CPU power consumption, to say that only measuring the current and voltage of the interface can not tell how to distribute the power, the motherboard with +5V is a lot of things.
Full text summary
In fact, the product positioning of Ryzen 5 8400F is similar to the Ryzen 5 7500F launched by AMD last year, both of which are products after removing the core display, and they are more cost-effective than the original, but the performance and market positioning of Ryzen 5 8400F are significantly lower than the latter, which can be seen from the frequency of the CPU and the pricing of the whole machine.
Ryzen 5 8400F is positioned as an entry-level gaming platform, and the benchmark is only Core i5-12400F/12490F This level of products, from the test results, its single-threaded and multi-threaded performance is stronger than that of Core i5-12400, after all, Ryzen 5 8400F has an absolute advantage in frequency, which is very important for gaming applications.
CPU Mini Ladder (Full CPU Ladder Leaderboard)
Since the Ryzen 5 8400F only ships to the OEM market and is not retail, it is difficult to evaluate its price-performance ratio alone. As far as the whole machine is concerned, the combination of Ryzen 5 8400F and RX 6750 GRE 10GB can provide similar gaming performance to the Core i5-12400 with RTX 4060, but the price is generally a few hundred yuan lower, the former can basically be won within 4000 yuan, and the price of the latter is generally above 4000 yuan, the combination of the former is significantly more cost-effective, plus quite a lot of Core i5-12400F The whole machine is equipped with a single DDR4-3200 With 16GB of RAM, the performance loss at a single channel is much higher than that of the Ryzen 5 8400F.
AMD's Ryzen 5 8400F this time provides a cost-effective entry-level game processor for the channel OEM machine market, judging from the current price of various brands of machines, AMD should be supplied to channel brands at a fairly favorable price, consumers can buy a lower price of less than 4000 yuan with RX 6750 GER 10GB AM5 machine platform, and there is good game performance, which is quite competitive at this price. Of course, the whole machine at this price can't avoid subsequent expansion and upgrading, you can see your own needs and wallet operation.
