Gaming index (Ryzen 7 9800X3D = 100) against the processors closest to it.
The Core i7-3820 scores 19 on our gaming index, where the Ryzen 7 9800X3D is 100. That puts it #169 of 239 processors we track, in E tier. It is slow by current standards, and recent games will often run well below what the graphics card can do.
It has 4 cores and 8 threads, boosting to 3.8 GHz. With 4 cores, the newest games will stutter or limit your frame rate, because they are built for six or more.
The Core i7-3820 uses the LGA2011 socket, so it fits motherboards with that socket. It is the fastest chip we track on that socket, so there is no drop-in upgrade.
It is rated at 130 W. Intel and AMD chips at this level draw well above their rating when they boost, so budget for a good tower cooler or a 240 mm liquid cooler and a power supply with headroom.
At 1080p, where the processor matters most, the Core i7-3820 can feed a card up to the GeForce RTX 3050 before it starts to hold the card back by more than 10 percent. At 1440p the limit moves to the GeForce RTX 5050 Laptop. At 4K, where the card does most of the work, it can keep up with the GeForce RTX 4060 Ti 16GB.
The Core i7-3820 is old or low power. Expect new games to run poorly, and look at an upgrade before you buy a new graphics card.
Graphics card performance index it keeps up with at each resolution.
The Core i7-3820 is a E-tier gaming processor: #169 of 239 in our list, with 4 cores and 8 threads up to 3.8 GHz. At 1080p it can feed a card like the GeForce RTX 3050 without a CPU bottleneck above 10%, and at 1440p a GeForce RTX 5050 Laptop.
At 1080p it can feed a card like the GeForce RTX 3050 without a CPU bottleneck above 10%. At 1440p, a card like the GeForce RTX 5050 Laptop is a reasonable ceiling.
