AMD Ryzen™ 5 3400G w/ RADEON™ RX VEGA 11 Graphics, AM4, Zen+, Quad Core, 8 Thread, 3.7GHz, 4.2GHz Turbo, 4MB, 65W, CPU is rated 5.0 out of 5 by 9.
Rated 5 out of 5 by from A good Allrounder if you need a CPU with onboard GPUfro thouse small builds

Rated 5 out of 5 by from World of Warcraft runs nicely on medium settings I bought two of these CPUs running in 2 slightly different setups. Motherboard, bios version, memory the same, cooling and case different. Using the integrated graphics in both. I haven't tried the stock cooler, instead I bought two bigger coolers, one with a 12cm fan with a big pc case and a smaller with a 9.2cm fan for a smaller case. I've found that the GPU clock and performance is dependent on the gpu/cpu temperature and the cooling. Using a smaller or stock cooler might affect the performance so make sure you get the right fan speed settings in bios. You should get a mostly constant 1400Mhz on the gpu while gaming after some warmup period to avoid stuttering gaming. I've checked/graphed up the Gpu clocks and temperatures with Hwinfo, but any other free hardware monitoring software should work. World of Warcraft runs 40+ fps on average without stutter on middle setting (5 on slider in settings), and goes up to 80fps in open spaces with less action. Just had to adjust the fan speeds slightly on the smaller cooler.

Rated 5 out of 5 by from Good bang for the price Great entry level processor, with plenty of grunt for my Son's first PC. Also gives us the option to upgrade later and add a separate GPU when the time comes. Decent fan with pre-applied Thermal Paste
Date published: 2020-07-27
Rated 5 out of 5 by from Excellent processor Super quiet fan. Excellent performance. Performs amazing with everything I have asked of it. The integrated graphics are brilliant. Every game I've played has been faultless. I would highly recommend the 3400g to anyone who was into casual gaming and not looking for the top of the top frame rates etc. Save yourself the extra cash and buy one of these. Simple and easy straight out of the box. Some minor tweaking but on the whole it does it all for you. It comes ready with thermal paste too so no need to buy one beforehand

Rated 5 out of 5 by from AMD Ryzen 5 3400G Excellent lightening fast delivery from Scan! Very happy with the Ryzen 5 3400G APU installed it with no problems and now working a treat in a ASRock DeskMini A300 (also from Scan). Highly recommend for a mini-desktop set up!

Rated 5 out of 5 by from Great value product Used this processor in my sons budget gaming setup. Setup was easy and the product itself was well made. Performing well in the setup also.

Rated 5 out of 5 by from Best value, excellent budget option Delivery was fast and well packed. Installing went easy with no problems. Storage: Yes, having a Ryzen 3000 series or newer (if you read this much later than originally posted) is required to take advantage of the PCIe lanes that make your NVMe work up to 5000 MB/s (read) and 4400 MB/s (write). Graphics: Comparing this £120 Ryzen 3400G to the £1200 RTX 2080 TI: Techpowerup ranks 10x of relative higher performance on the RTX 2080 TI (see image attached). Makes sense, as it's 10x more expensive, except the Ryzen 3400G is a great CPU as far as I can tell. As a game and software developer specializing in graphics programming, the main indicator to me of graphics overall performance is FP32 (float) performance, aka Single-Precision Performance. Unless you do a lot of matlab or other high precision calculations, then it's FP64 (double). Games (almost always) and even machine learning uses FP32 (float) operations. RTX 2080 TI - 13.45 TFLOPS (Techpowerup) Ryzen 3400g - 1.915 TFLOPS (Aida64 trial test I ran, see image attached) Ryzen 3400g - 1.746 TFLOPS (Techpowerup) Other numbers are also indicators as well, but only if know how to put them into context as to compare how well a specific task can be performed, but I'll let you explore them in your own research: Pixel Rate (post processing and screen-space effects), Texture Rate (texture mapping, multisampling, Shader Units (complex 3d blending, morphing, general effects and functionalities executed in the shaders) Expansion: Provided you have a PSU of 600w or more, you can later expand your computer's power by replacing this modest APU with a Ryzen 9 3950X, 16 Cores / 32 Threads, 3.5GHz base / 4.7GHz turbo and add your favourite discrete gpu, without having to change anything else, maybe just a watercooler.

Rated 5 out of 5 by from Am Impressed Matched this APU up with an Asus B450 with 16gb ram as I basically needed integrated graphics for a work pc running through an ASD. Installed a couple of games I usually run on my gaming rig and was impressed of how nice this one runs the games. Recommend this one as a great start for an entry level gaming pc..

Is it a wraith Stealth Cooler

Hi, Your product description states a Wraith Spire, but the text describes a Wraith Stealth cooler? I want to purchase to fit your Asrock A300 which needs the stealth cooler.
Asked by: Syfer

Will the 3400g support a dual monitor set up?

Will this support dual monitors provided the Motherboard has a hdmi and display port. No gaming intended. Just office work.
