[HELP] Powercolor RX 6500 XT capped at 60 fps

[kanamari]

Hello everyone, I need some help here as my GPU capped at 60 fps. I install new RX 6500 XT GPU to replace my broken RX 580. With my previous GPU, I can get 100++ FPS when playing games (DOTA 2, Manor Lord, etc). But with RX 6500 XT it seems fps capped to 60 fps because it is same whether I use low or high settings. I have disabled V-sync as well as downgrade my driver but no results. Here is my specs and driver

Processor : Ryzen 5700G
Motherboard : Asrock B450M-HDV R4.0 Bios 10.31
Memory : HyperX Predator 2x8 GB 3200 MHz
GPU : Powercolor RX 6500 XT 4GB Fighter
Storage: PNY CS 2241 1TB
Display: Viewsonic VA-2432-MH (HDMI Port) (100 Hz)
PSU : FSP HV Pro 650 Watt
Driver : 24.10.1 (was tried 24.7.1 but problem persist)

The card is a pcie 4x card vs 16 x is apart of it, plus it has way less shaders, TMUs

You basically went from a mid range card to a entry level

If that rx 580 was 8GB, the 6500xt has half the framebuffer at 4GB as well.

The RX 580 is still a competent GPU it's just obsoleted by feature lockout like DX12_2 and has issues with Vulkan.
The RX 6500 XT is a sidegrade move that even I would avoid and for good reason.

It's comparatively the exact same performance with worse specs, trading off acceleration abilities and introducing problems.
Shading Units: 2304 -> 1024
TMUs: 144 -> 64
Compute Units: 36 -> 16
L0: None -> 32KB/WGP
L1: 16KB/CU -> 128KB/Array
L2: 2MB -> 1MB
L3: None -> 16MB

DirectX: 12_0 -> 12_2
OpenCL: 2.1 -> 2.2
Shader Model: 6.7 -> 6.8

Pixel Rate(GPixel/s): 42.88 -> 90.08
TexRate (GTexel/s): 193 -> 180.2
FP16 (TFlops): 6.175 -> 11.53
FP32 (TFlops): 6.175 -> 5.765
FP64 (GFlops): 385.9 -> 360.3

That last one is especially ouch. I can go on but this is the hard impasse:
Memory Type: GDDR5 -> GDDR6
Memory Size: 8GB -> 4GB
Memory Bus: 256-Bit -> 64-Bit
Bandwidth: 256GB/s -> 143.9GB/s

So it's effectively the same performance at half the bandwidth and power.
The clock speeds and pixel rate are good but the rest has me looking the other direction.
What pushed you towards the 6500 XT? Noise? Less power draw = less heat?
It definitely has some good points to it but a move like that from a 580 has me wondering why.

I have tested a Powercolor 6500XT 4GB vs. an MSI RX580X 8GB. Most (not all) scenarios, the 6500XT was SLIGHTLY faster.
The exceptions were games like Avatar: Frontiers of Pandora and Read Dead Redemption 2, that use a ton of VRAM.
Though, that was on my X570 Chipset's x4 4.0, not PCIe 3.0 (5700G/Cezanne limitation); Which, does downgrade the 6500's performance some.

According to TPU's research, a PCIe 3.0x4 connected Navi24 is slower than a baseline 580 (but, on 4.0x4, is single-digit percentage faster. (In-line w/ my experiences)


Edit: Make sure "Radeon Chill" and FrameRateTargetControl are both disabled. IIRC, Chill is on by default on the 6500XT.

I see OP has an APU. Is it disabled? (it doesn't *have* to be)
Asking, as I used a 6500XT and a Vega together, on Win11 for AFMF+pass-thru.

Make sure that Windows isn't trying to render on the iGPU and that your primary display isn't connected to the mobo.

So You saw what I was getting at. If anything the 6500xt is like the new RX 560D or RD 470D.

Aye. OP's 5700G limits them to PCIe 3.0, and any of those would've been a true upgrade.
Even on an ideal Gen4 platform, the 6500XT is a 'sidegrade' from the 580, at best.

On the bright side, the Navi24 6500XT is mobile-derived, and can be tuned to absolutely sip power. -Probably not what OP had in mind, though.

He is looking for higher fps and he isnt getting it with that card on that cpu so he is bandwidth limited because of both.

He has 3 options, try a non igp based cpu, change card, or do both at the same time.

If returning/reselling the 6500 isn't an option, a <$200 5700X3D would resolve all issues in-play and provide the 'felt' upgrade they were looking for.
+Gen4 PCIe*, the 6500XT becomes *slightly* faster than their old 580
+The 5700X3D is a considerably more-potent CPU, especially for gaming. (Meaning there would be a decent 'felt' performance uplift, overall)
+It would be the last and highest performance (viable) CPU upgrade for the platform (5800X3D disconn'd and @ scalper pricing in secondary market)

Edit: *just realized OP is on B450.
I don't think there's any 'hacked' firmware to allow Gen4 on those, even tho B550A proved it was capable.
Return/Resell or mobo(B550)+cpu(5700x3d) upgrade. :/

If price is right a 5800 oem (what the 5700X retail is originally) would work due to no busing issues.

Anyways need to wait on op to return, if they do that is...

He can also sell the 6500xt.

Good budget/general recc.

Personally, the X3D is worth it, and gives the AM4 platform just a lil more/longer 'legs'.
Issue is, they're on B450. Even w/ a 5000series, no Gen4 w/o a diceroll on an archaic AGESA-release firmware, or modded firmware.

Sadly, the 6500 XT just was not a reasonable choice for their current build.

Sometimes asrock have helped users with a firmware to fix an odd issue from time to time...

It be budget that determines a system overall build, but there are caveats if it isn't large enough.

A build in 2021 I did, the 3d chips weren't out and I got the 5800 oem at $262 after calling seller out for trying to sell it as a 5800X, he returned $100 which was fine. I can max the ram out, do a cpu upgrade and if user ever got into gaming, remove the XFX R7 250X Ghost and put a RX 5500XT or better in.

Wow thanks everyone, I really appreciate it.

It definitely has some good points to it but a move like that from a 580 has me wondering why.

My card was RX 580 4GB, and yeah I was satisfied with the card performance (except for its loud noise and heat), thus I just wanna do 'sidegrade' move as I only casual gamers and rarely do it. Current 60 FPS is actually fine but I am just wondering because it looks like 'capped' somewhere (moving image quality from lowest to highest didn't change FPS numbers, 60 FPS).

According to TPU's research, a PCIe 3.0x4 connected Navi24 is slower than a baseline 580 (but, on 4.0x4, is single-digit percentage faster. (In-line w/ my experiences)

Yeah, I was completely forgot about PCIe gen when considering 6500, but I didn't expect the difference would be that high, I thought it would be 10-20% difference. APU is not disabled, and I connect my display to the GPU. FRTC are disabled, but I need to check about Radeon Chill

Aye. OP's 5700G limits them to PCIe 3.0, and any of those would've been a true upgrade.

I was expecting sidegrade move, with less heat and noise. But PCIe gen hinder that.

Well price is some point, but I am not looking for higher fps, just GPU with similar performance with RX 580, I was ok with its performance. I change from RX 580 to RX 6500 XT primarily because it was broken

For next upgrade probably changing it to AM5, as I consider it is only small leap to upgrade it to non iGPU 5000 processors and change the GPU if its laggy (below 60 FPS). Because I am using my computer mostly for watching movies and doing some work (you know, spreadsheet etc)

If price is right a 5800 oem (what the 5700X retail is originally) would work due to no busing issues.
Anyways need to wait on op to return, if they do that is...

He can also sell the 6500xt.

Well, i thought 60 fps was caused by driver or settings related issues, but if it is caused by hardware issues, I am fine with it as 60 fps



Thank you for the suggestions, now i know it is hardware-related issues not driver or settings. Cheers
