In this full-day testing of motherboards we aim to verify our very own launched Tracer B450M-D4 Pro motherboard as well as the similar motherboards in the market.

Motivation

Although our strict quality checks and verification of test samples before bulk-order ensure that we receive and provide the best possible quality material for our customers at best prices, we saw a surge in troll crowd and discouraging opinions across multiple social media platforms mainly, reddit and facebook. This forced our hand to pit one of our motherboards against the market veterans. The hate and disdain we receive drives us to the point of rebellion against the ignorant troll mob and sofa warriors that never got the air of our products.

Comparison Models

We have total of 6 motherboards with the same test setup which are as follows:

1. Tracer B450M-D4 Pro
2. Gigabyte A520M-K V2
3. Gigabyte B550M-K
4. MSI Pro B550M-B
5. MAXSUN B550M Gaming Wifi
6. ASUS Prime B450M-K

Testing Methodology

As previously mentioned, the motherboards carry a standard test setup of:

• AMD Ryzen 7 5800X CPU
• 32GB 16×2 PUSKIL 3200MHz CL18 DDR4 RAM
• Motherboard
• SAMA 360mm AIO CPU Cooler
• AMD Radeon RX 7800 XT GPU (for display)
• Enclosed in a PC Case with 3x Corsair AF120 LED Fans as intake, 1x Corsair AF120 LED Fan as exhaust and 3x AIO fans on exhaust

During whole testing procedure, the case window was closed. The benchmarking software used is Cinebench R23 Multicore on 10 minutes test. Near the end of each test we’ll open the window of the case and check for highest temperatures at the back of the motherboard PCB where the VRM are situated. We’re also using PMD2 power measurement module to check for the CPU power consumed in-line as well as checking for dips in CPU clocks as well as power consumption. This will give us an absolute idea about thermal throttling, CPU limitation as well as power throttling.

Observations

The whole testing video is uploaded on our youtube channel so we’ll reference our findings right from the video here in the stress test performance & comparison table.

We found out that Tracer B450M-D4 Pro was able to sustain 130W CPU power with absolutely no throttling as well as VRM temperatures observed to be at 80°. The Cinebench R23 Muilticore score at the end of 10 minutes test was 14730 which is well within acceptable range for Cinebench R23 Multicore scores from the online database. Next in the testing lineup Gigabyte A520M-K V2 started CPU throttling because of VRM overheating upto 130°C within the 5 minutes of the test with the CPU clocks dipping as low as 1.6GHz as well as CPU power dropping to 30W. It was useless to note the cinebench score at this point but we went ahead with taking an individual cinebench multicore score anyway and found it out to be 12824 which is a significant drop. The third motherboard Gigabyte B550M-K refused to give full power to Ryzen 7 5800X and was locked at 60W despite our efforts to force the PPT, TDC and EDC values via PBO as well as specifying the CPU power to be 105W. We left it as as since we were testing the motherboards right out of the box. The cinebench R23 multicore score for Gigabyte B550M-K dropped further into Ryzen 5 5600X territory, turning out to be 10893. Fourth motherboard MSI Pro B550M-B held stable performacne with supplying 150W of CPU power with VRM max temperatures observed to be 94°C. Cinebench score at the end of the test was 15124 points. Fifth motherboard MAXSUN B550M Gaming Wifi turned out to be the top dog, supplying 180W of CPU Power (we’ll get that checked out with the manufacturer) with VRM temperatures standing at respectable 81°C, with the cinebench R23 multicore score of 15184 points at the end of 10 minutes test. Last in the line, ASUS Prime B450M-K stayed borderline with VRM temperatures hitting 116°C although no throttling was observed during the 10 minutes test with cinebench R23 score of 15,048.

The findings are tabulated with the timestamp references from our testing video as below.

Stress Test Performance & Comparison

Motherboard Model	Market Price (Approx.)	Power Delivery / VRM Status	Peak VRM / PCB Temp	Cinebench R23 Score	Key Takeaway
Tracer B450M-D4 Pro (AMD House)	~20,000 PKR	Stable ~128W–136W	~80°C	14,730	Maintained full performance with safe, stable VRM temperatures under sustained load. [12:47]
Gigabyte A520M K V2	~19,500 PKR	Heavy Throttling (Spikes from 129W down to 33W)	~127°C	Dropped Significantly	No VRM heatsink. Severe thermal throttling caused massive processor clock drops down to 1.6GHz within 5 minutes. [16:58]
Gigabyte B550M K	~25,000 PKR	Strictly Power-Locked at 60W	Low (due to lock)	Massively Dropped	Factory-locked via microcode/BIOS. The board refuses to feed the CPU full power, heavily capping performance out-of-the-box. [21:37]
MSI Pro B550M-B	~25,000 PKR	Stable ~150W	~94°C	15,124	Good power delivery and handled the chip fully without throttling, though ran significantly warmer than the Tracer board. [28:06]
Maxon B550M Gaming Wi-Fi	~25,000 PKR	Stable ~180W	~80°C	15,184	Robust 4+2 phase power design with solid heatsinks. Offered premium performance and cool operation. [33:01]
Asus Prime B450M-K	~21,000 PKR	Sustained Full Power	~116°C	15,048	Achieved an excellent baseline score without throttling, but the VRM temperatures reached dangerous border-line limits. [36:36]
